To switch IT providers without disruption, take back ownership of your accounts and data first. Then run both providers side by side for a short overlap, and remove the old provider’s access only after everything’s checked.
If you’re reading this, there’s a good chance your current IT provider has stopped earning your trust. Maybe they flagged problems months ago and never fixed them. Maybe tickets go unanswered, or you’ve stopped calling because it doesn’t seem worth it.
The thing that keeps most businesses stuck isn’t loyalty. It’s the fear that leaving will break something: email going down, files going missing, or a provider who won’t hand over the passwords.
That fear is reasonable, but it’s manageable. A well-planned switch is mostly invisible to your staff. This guide walks through exactly how to do it, including the Australian-specific details most switching guides miss.
When is it time to switch IT providers?
It’s time to switch when problems are reported but not fixed, response times keep slipping, you can’t see what you’re paying for, or your provider can’t support where your business is heading, such as security, compliance or growth.
We’ve covered the warning signs in detail in 7 signs your Sydney business needs managed IT services and 10 warning signs your business has outgrown its IT setup.
The short version: if you’re managing your IT provider more than they’re managing your IT, something has to change.
What does your old IT provider control that you need back?
Often more than you think. Your domain name, Microsoft 365 admin access, software licences, backups, phone numbers and network passwords may all be registered to or held by your provider. Get control of these before you give notice.
This is the step that makes or breaks a switch. Many businesses discover, mid-transition, that their provider registered the domain using its own email address, or holds the only global admin account for Microsoft 365.
None of this is necessarily sinister. It’s often just how the provider set things up years ago. But it means your business doesn’t fully control its own systems, and that needs fixing whether you switch or not.
Here’s what to check:
| What to check | Where it often sits | How to take it back | Who should hold it |
|---|---|---|---|
| Your .au domain name | Registered through the provider’s reseller account, sometimes with the provider’s email as the registrant contact | Check the registrant details on a WHOIS lookup. The transfer code is sent to the registrant email, so update it to an address you control. auDA can also search for every .au name registered to your ABN or ACN | Your business, with a registrant email you control |
| Microsoft 365 admin access | Global admin accounts created and held by the provider | Create a global admin account for a named person in your business, with multi-factor authentication, before you give notice | Your business, plus limited access for your provider |
| Microsoft 365 partner relationship | The provider’s partner admin roles in your Microsoft 365 tenant | Review them in the Microsoft 365 admin centre under Settings, then Partner relationships. You can remove a partner’s roles there | Only your current provider, with only the roles it needs |
| Software licences | Bought through the provider’s Microsoft or vendor reseller account | Ask for a licence list with renewal dates, and plan the transfer so licences don’t lapse at cutover | Your business, billed through your chosen provider |
| Backups | Stored in the provider’s own backup platform or cloud account | Confirm where every backup lives, who owns the storage, and test a restore before the old provider leaves | Your business, with the backup account in your name |
| Phone numbers | Held by the provider’s telco partner | Port them to your new provider. Keep the old service active until the port is complete | Your business, as the customer of record |
| Network devices and passwords | Firewalls, Wi-Fi and switches configured with passwords only the provider knows | Request all admin credentials and configuration backups in writing, then change every password after handover | Your business, in a password vault you control |
A few of these are worth explaining.
Domain names. auDA, which runs the .au domain, says there’s no fee to transfer a .au domain between registrars, and the transfer code is sent to the registrant email address recorded in the registry (auDA). If that email belongs to your old provider, sort it out early. auDA can also search across all accredited registrars for .au names registered using your ABN or ACN, and says it responds within 14 calendar days (auDA).
Microsoft 365. Microsoft lets you see which partners have admin roles in your tenant, and remove those roles yourself, from the Partner relationships page in the Microsoft 365 admin centre (Microsoft). Removing admin roles doesn’t automatically end a partner’s reseller relationship or any Azure role assignments, so check those separately.
Phone numbers. The Australian Communications and Media Authority says you can usually keep your phone number when you change telco, a process called porting (ACMA). The practical rule: never cancel your old phone service before the port is complete.
How do you switch IT providers step by step?
Secure your accounts, choose and brief your new provider, give notice, run a short overlap for the handover, cut over, remove the old provider’s access, then work through a prioritised list of fixes in the first 90 days.
1. Secure your access before anything else
Before you tell your current provider anything, make sure your business holds its own admin access to Microsoft 365, your domain and your key systems. This is your safety net if the handover gets difficult.
2. Gather what you can find
Pull together your current contract, recent invoices, a list of staff and devices, and any documentation your provider has shared. Check your contract’s notice period and termination terms, because these set your timeline.
3. Choose and brief your new provider
Shortlist providers and ask each one to explain exactly how it runs a transition. If it can’t describe its process in detail, that tells you something. Our guide on how to choose a managed IT provider in Sydney covers what to look for, and our breakdown of managed IT services cost
4. Give notice, in writing
Notify your current provider in writing, in line with your contract. Include a written list of what you need handed over: credentials, documentation, licence details, backup locations and configuration files. Give them a date.
5. Run a short overlap
Your new provider should start discovery while your old one is still responsible for support. This overlap lets the new team learn your environment, install its monitoring tools and confirm it has every credential before taking over. Your staff keep calling the same number until the cutover date.
6. Cut over on a planned date
On the agreed date, support moves to the new provider. Staff get one clear message: who to contact from today, and how. For a well-planned switch, that’s often the only change they notice.
7. Remove the old provider’s access
Only once the new provider confirms everything works should you shut the old provider out. We cover how to do this safely below.
8. Work through the first 90 days
Every switch turns up issues: unpatched devices, untested backups, accounts that should have been closed. A good new provider documents these and fixes them in priority order.
How long does it take to switch IT providers?
Plan for several weeks from choosing a new provider to completing the handover. The biggest factors are your current contract’s notice period, how well your systems are documented, and how cooperative your outgoing provider is.
The technical cutover itself is usually quick. What takes time is everything around it:
- Your notice period, which is set by your current contract
- Discovery, which takes longer when there’s little documentation
- Licence and phone transfers, which run on vendor and telco timeframes
- The outgoing provider’s response time when you request credentials and documentation
When is the best time to switch IT providers?
Switch during your quietest period, never during your busiest. Avoid end of financial year, major deadlines and audits. If you’re moving office or renewing your phone and internet contracts, line the switch up with that.
A few timing points specific to Australian businesses:
- Avoid 30 June. End of financial year is the wrong moment to change who supports your finance systems.
- Accounting and bookkeeping firms should avoid peak lodgement periods.
- Professional services firms should steer clear of major matters, audits or tender deadlines.
- Moving office? Combine the two. An office relocation already means new networking, internet and phones, so switching providers at the same time avoids doing the work twice.
- Phone or internet contract ending? That’s a natural point to bring your Business NBN and VoIP phone system across in the same transition.
What if your current IT provider won’t cooperate?
Rely on the access you secured in step one. Put every request in writing with a deadline, check your contract’s exit clauses, and let your new provider work directly with Microsoft, your registrar and your telco.
Most providers hand over professionally. Sometimes, though, the relationship has soured, or the provider is simply slow. Here’s how to protect yourself:
- Don’t depend on goodwill. That’s why step one, securing your own admin access, comes before giving notice.
- Document every request. Send handover requests by email with a clear list and a reasonable deadline.
- Check your agreement. Many contracts include obligations around handover and the return of your data. Quote the relevant clause.
- Go direct to vendors. Your new provider can often work with Microsoft, your domain registrar and your telco to recover access, because those accounts belong to your business, not your IT provider.
- Escalate if needed. If your telco services are involved and a complaint can’t be resolved with the provider, the Telecommunications Industry Ombudsman handles complaints about phone and internet services.
How do you remove your old provider’s access safely?
Remove their Microsoft 365 partner roles, disable every account they used, uninstall their remote access and monitoring tools, change all shared and admin passwords, and confirm nothing still connects back to them.
This is the step most businesses forget, and it’s a real security risk. The Australian Signals Directorate notes that managed service providers have access to an organisation’s systems, networks and data (ASD’s ACSC). When a provider leaves, that access needs to leave with them.
Work through this checklist with your new provider:
- Remove the old provider’s roles from your Microsoft 365 partner relationships
- Disable or delete every account the old provider used, in Microsoft 365 and on your network
- Uninstall the old provider’s remote access and monitoring software from every device and server
- Change admin passwords on firewalls, Wi-Fi, servers and any shared accounts
- Update the registrant email on your domain to an address you control
- Revoke any VPN access or certificates issued to the old provider
- Check scheduled tasks, mail forwarding rules and app permissions for anything that still points to them
Leftover remote access software is a common blind spot. An old provider’s tool that’s still running on a laptop is a doorway nobody’s watching.
Once access is cleaned up, it’s a good time to review your tenant’s baseline. Our article on Microsoft 365 settings worth checking is a useful starting point.
What should your new provider do in the first 90 days?
Give you a written list of every issue it found during the switch, ranked by risk, with an owner and a target date for each. Then report progress against it, so problems get fixed rather than just noted.
This is where a switch pays off, or doesn’t. If your last provider identified problems and never acted on them, the first 90 days with your new provider should look completely different.
Expect your new provider to:
- Document your environment properly, often for the first time
- Test your backups with a real restore, not just a green tick on a dashboard
- Close security gaps such as missing multi-factor authentication, unpatched devices and old accounts
- Turn on monitoring across your devices and Microsoft 365, ideally from day one
- Hand you a prioritised findings list, with owners and dates, and report against it
How does TECHD Group handle a switch?
TECHD Group runs every switch as a planned project. We secure your access, manage a structured handover from your old provider, and can move your internet, phones and mobiles at the same time, so you deal with one team.
Our Managing Director, Ben Neighbour, has worked on both sides of IT handovers, at managed service providers and leading internal IT teams for private businesses. TECHD Group was founded in 2019 to fix exactly the multi-vendor mess that makes switching feel hard.
Here’s how we approach it:
- IT assessment. We review your environment, your contract and every technology bill you pay.
- Ownership audit. We help you secure your domain, Microsoft 365 admin access, licences and backups before you give notice.
- Planned handover. We coordinate directly with your outgoing provider, so you don’t have to chase them.
- One transition for IT and telco. If you choose, we bring your NBN, phone system and mobiles across at the same time, porting your numbers so callers notice nothing.
- Protection from day one. Our 24/7 Security Operations Centre starts monitoring your devices, Microsoft 365 and firewall logs as soon as we’re in.
- A written findings list. Every issue we find is ranked, owned and reported on, so it gets fixed.
We’re based in Manly with on-site support across Greater Sydney, and TECHD Group is a member of the Telecommunications Industry Ombudsman scheme.

Frequently asked questions about switching IT providers
Can I switch IT providers before my contract ends?
Usually, yes, but check the termination clause first. Many managed IT agreements set a notice period or minimum term, and some charge for leaving early. Read your agreement before you give notice, then plan the overlap with your new provider around that date, so you’re never left without support.
Will we lose emails or files when we change IT provider?
You shouldn’t. Your email and files live in your own Microsoft 365 or Google Workspace account and on your systems, not with the IT provider. A switch changes who manages them, not where they’re stored. The main risk is backups held in the old provider’s account, so confirm and test those first.
When should we tell our current IT provider we’re leaving?
After you’ve secured your own admin access and chosen your new provider, but before the notice deadline in your contract. Telling them too early can leave you in a long, awkward wind-down. Telling them too late can mean paying for overlapping contracts or rushing the handover.
Can we keep our phone numbers if we switch IT and phone providers?
Usually, yes. Australia’s communications regulator, the ACMA, says you can generally keep your number when you change telco, a process called porting. Keep your existing phone service active until the port is complete, and confirm your new provider can take your numbers before you sign.
Who should own our domain name and Microsoft 365 admin accounts?
Your business should. Your domain should be registered to your company, with a registrant email address you control. Your business should also hold its own Microsoft 365 global administrator account, with a backup. Your IT provider should work through its own separate accounts with only the access it needs.
