How to Switch IT Providers Without Downtime

Most businesses stay with an IT provider they’ve outgrown for one reason: they are more afraid of the switch than they are of the status quo.

It’s a reasonable fear. Your current provider holds your domain registrar logins, your Microsoft 365 tenant, your firewall configs, your backup keys, and a mental map of how everything is wired together that exists nowhere in writing. Handing that over badly means an outage — and outages during a provider change are the kind everyone remembers.

But a properly run handover doesn’t cause downtime. Here’s what one actually looks like.

Before you give notice: get your inventory

Do this while you are still a paying customer, because your leverage disappears the moment you send the termination email.

You need a written list of:

• Every domain you own, and which registrar holds it
• Your Microsoft 365 or Google Workspace tenant, and who holds Global Admin
• Firewall, switch, and access point makes, models, and admin credentials
• Where backups are stored, how far back they go, and when a restore was last tested
• Every software licence and its renewal date
• ISP account numbers and support contacts
• Any custom scripts, automations, or monitoring agents running on your machines

If your provider can’t produce this in a week, that’s your answer about whether leaving is the right call.

Check who actually owns what

This is where handovers go wrong.

A lot of providers register domains, buy licences, and set up cloud tenants under their account rather than yours. It’s not always malicious — it’s often just how they onboarded you years ago. But it means the asset is legally theirs, not yours, and it becomes a negotiation instead of a transfer.

Check three things specifically:

1. Domain registrar — is the registrant your company, or the MSP?
2. Microsoft 365 / Google Workspace tenant — is it a direct tenant, or are you a customer under their CSP partner account?
3. Licences — bought in your name, or resold through them?

If any of those are in the provider’s name, sort it out before you give notice.

The overlap period is not optional

Do not terminate on the 31st and start with someone new on the 1st.

A safe changeover runs two to four weeks of overlap, where the incoming provider has read access and is documenting your environment while the outgoing provider is still contractually on the hook. You pay both for a few weeks. It’s the cheapest insurance you will ever buy.

During overlap the new provider should be:

• Deploying monitoring agents and confirming they report correctly
• Documenting the network before touching anything
• Testing a restore from your existing backups — not assuming they work
• Identifying anything undocumented that only lives in the old provider’s head

What to put in the termination letter

Keep it unemotional and specific. Ask for:

• A written handover of all credentials, in a password manager export
• Transfer of domain and tenant ownership by a named date
• Confirmation of which licences transfer and which lapse
• Removal of their remote access tools from your machines by a named date
• A final backup, verified restorable, handed to you

That last one matters. Getting a backup file is not the same as getting a backup you can restore from.

Red flags during the handover

• “We’ll send credentials after the final invoice clears.” Credentials are your property, not collateral.
• No documentation exists. If it was never written down, budget for the new provider to rediscover your entire environment.
• Remote access tools still installed weeks later. A former provider with live access to your machines is a security incident waiting to happen.
• Backup restores that were “never actually tested.” Very common, and it is worth finding out now rather than during a ransomware event.

A realistic timeline

Five weeks, no downtime, nothing lost.

The part most people get wrong

They treat switching as an IT project. It isn’t. It’s a records transfer with an IT component. The technical work is straightforward. The part that goes wrong is ownership, documentation, and access — paperwork, essentially.

Get the paperwork right and the technical side is uneventful. Which is exactly what you want a provider change to be. If you’d rather have the incoming side handled for you, that’s what our managed IT service does on every takeover — the handover is our job, not yours.

Free Handover Readiness Check

Before you give notice, find out what you’re actually holding. We’ll go through your current setup and tell you, in writing:

• Which domains, tenants, and licences are in your name and which are in your provider’s
• What’s documented and what only exists in someone’s head
• Whether your backups actually restore

Takes about 30 minutes. No obligation, no sales pressure — and if the answer is that your current provider is doing a good job, we’ll tell you that.
