Changing IT Providers: How to Switch to a New IT Company Without Downtime

In short:

• Before you announce the switch, check whose name the domain, the admin accounts and the licenses are in.
• Ask for a full list of access, documentation and backups - and check that the backups actually restore.
• The new provider first reviews your environment and only then takes responsibility for it.
• After the transition, change the passwords and close all old access, including remote access tools.

When it is time to change your IT provider

There is rarely one big reason. More often, small signs pile up:

• The same problems come back every week and nobody looks for the cause.
• You do not know how quickly they will respond, and when something stops, you wait.
• There is no documentation: it is unclear what is on the network, who has admin access and where the backups are.
• You hear about problems from your staff, not from the provider - nobody is monitoring the systems.
• Security is discussed only after an incident.
• The company is growing - new people, a new office, Microsoft 365, NIS2 requirements - but the support stays the same.

If you recognize three or more of these, it is worth having another team review your environment. If you are not sure who to choose, see how to choose an external IT partner.

The biggest risk: the access is not in your name

Before anything else, check who actually controls the key systems. Over the years, everything has often been set up in the provider's name or in the name of one employee who has since left.

Check whose name these are in:

• The domain and access to the DNS settings - your website and email depend on them.
• The global admin account in Microsoft 365 or Google Workspace.
• The licenses for Windows, Office, antivirus protection and business software.
• The firewall, router and Wi-Fi - who knows the passwords and is there a backup of the configuration.
• Hosting, cloud services and supplier accounts (internet, telephony, software portals).

The goal is simple: everything the business cannot run without should be in the company's name, and the provider should have access, but not the only access.

What you should get from your current provider

Ask for the handover in writing, as a list. That way nothing stays "in the head" of someone who will not be answering a week from now.

If some of this is missing, that is no reason to postpone the switch. The new provider can rebuild the picture by reviewing the environment - but they need to know in advance that they will have to.

The switch in 6 steps

1. Review the environment before the takeover

The new provider should first see what they are taking over: computers, operating systems, licenses, servers, network, protection and backups. That way the risks surface before the transition, not after it. In our case study on an IT audit when onboarding a new client, the client believed "everything works", but the review found systems out of support and unlicensed software.

2. Take control of the key access

Create a separate admin account in the company's name for Microsoft 365, the domain and the firewall, kept in a safe place. The new provider gets its own accounts. Nobody works with the "shared" password.

3. Check the backups before you touch anything

Do a test restore of a file and, if you have a server, of a whole machine. If something goes wrong during the transition, these are the copies that will save you. More on this in our article on how to back up company data without risk.

4. A short overlap period

If possible, plan a few days when the old and the new team are both available. One handover meeting that goes through the list in the table above saves weeks of guesswork.

5. Change the passwords and close the old access

Once the new team has taken over, change the admin passwords, remove the old provider's accounts and its remote access tools from the computers and servers. Turn on two-factor authentication for all admins - see why businesses use MFA.

6. The first 30 days: monitoring and stabilization

The new provider installs system monitoring, sorts out the updates, documents the environment and fixes the riskiest things first. By the end of the month, you should have a clear picture: what has been fixed, what comes next and how quickly requests are resolved.

What to tell your staff

For your staff, the switch should be almost unnoticeable. One short message is enough:

• from which date requests go to the new team;
• how to submit a request - phone, email or a ticketing system;
• that they may be asked for brief remote access to their computer during the takeover.

If your current provider does not cooperate

It happens. It is important to know that the data and the accounts belong to your company. Most access can be recovered without their help: admin access to Microsoft 365 by proving ownership of the domain, the domain through the registrar with your company documents, network devices by resetting and reconfiguring them. This takes longer, which is why it is planned, not done on the last day.

How long the switch takes

It depends on the environment. For an office with a few computers and Microsoft 365, the transition is usually a matter of days. With servers, several offices or specialized software, it takes a few weeks, because each system is taken over and checked separately.

How we take over a new company at Helpdesk Bulgaria

We have been working with businesses since 2005. When we take over a new client, we follow the same order:

• We review your environment before proposing a solution: what you have, what is risky and what needs fixing first.
• We take over the access and document the environment, so that nothing depends on one person.
• We turn on 24/7 system monitoring, so we often see problems before you do.
• You have one contact for everything - computers, servers, network, Microsoft 365 and security.

We resolve 95% of requests the same day, most of them remotely, and come on site when needed. We work across Bulgaria, remotely and on site. See what our managed computer and IT support and server support include.

Frequently asked questions

Will work stop during the switch?

It should not. The takeover is done in stages, and the risky steps - such as changes to email or the network - are planned outside working hours.

What if passwords or documentation are missing?

The environment review rebuilds them. It takes a little longer, but it is better to do it now than at the first outage.

Do we have to replace our computers and equipment?

Not automatically. Only what is out of support or poses a real risk is replaced. Everything else keeps working.

How much does support cost after the switch?

We work mainly on a monthly subscription - from €20 per computer excl. VAT. The exact price depends on the number of computers, the servers and the response level you need. See all plans and prices.
