How to Switch IT Providers in NZ

When you switch IT providers, you do not necessarily move your email, files or servers. If hosting, licences or tools also need to change, plan those separately so the support handover is not confused with a wider migration.

This guide is for business owners and managers in New Zealand who plan to switch IT providers, or who are weighing whether to. It covers what is changing, the checks to complete before giving notice, the handover steps, a checklist for closing the handover, who is responsible during the transition, and what affects timing and cost. The aim is a controlled decision, whichever provider you choose.

What changes when you switch IT providers?

Start by deciding what is changing. When businesses switch IT providers, the change can mean several different things, and each needs its own plan.

• Who supports the environment. A new provider takes on management responsibility for the systems you already have. Staff accounts, files and email can stay where they are.
• Where systems run. Moving servers, hosting or file storage to a new location is a migration project, separate from the support change.
• The products you use. Replacing backup, security, remote management or phone systems means new tools and a controlled changeover.
• Several of these at once. Combining changes is possible, but each part needs its own sequence, testing and approval.

Taking over management of an existing Microsoft 365 tenant, for example, may leave staff accounts and data in place. Moving to a new hosting platform or replacing a backup product is different work, with its own risks and its own schedule. Keeping these separate stops onboarding from turning into an infrastructure project nobody planned for.

When you switch IT providers, ask the incoming provider to say clearly which category each part of the proposed work falls into. If a proposal bundles a support change with a hardware refresh or a hosting move, ask whether those parts are needed now or could follow later, once the new support arrangement has settled.

Can you change IT providers without downtime?

A support handover can be completed with little disruption, especially when the systems themselves stay in place. Some changes still need a maintenance window. Agree what will change, who is responsible, how it will be tested and what happens if a step fails before committing to the cutover.

When you switch IT providers, the aim is to minimise disruption, not to promise none. A planned interruption outside business hours can be part of a well-run handover. For each change that affects staff, agree the following.

• The window. When the change happens and how long the affected service may be unavailable.
• Approval. Who in your business signs off the change before it goes ahead.
• Communication. How affected staff are told, and who they contact if something is not working afterwards.
• Testing. What is checked after the change to confirm the service works as expected.
• Fallback. How the work is stopped or reversed if a step fails, where reversal is possible.

A good handover keeps the business supported and protected throughout, with any interruptions planned and agreed in advance. It is not measured only by whether staff notice the date the provider changed.

What should you check before you switch IT providers?

Before you switch IT providers, review the contract with your current provider and choose the incoming provider. Giving notice first can leave the business without support if the new arrangement is not ready.

Review the current agreement

Read the notice period, renewal dates and any minimum term. Check what exit or handover assistance the agreement includes and whether it is charged separately. Note any licence commitments, leased equipment or supplier tools that sit with the outgoing provider, and what happens to each when the agreement ends.

Confirm your business controls its own accounts

Your business should retain control of its Microsoft 365 tenant, domain names, data and recovery arrangements. Check who holds the global administrator accounts, who the registered contacts are for your domains, and whether recovery email addresses and phone numbers belong to your business rather than to the provider. If any of these sit only with the outgoing provider, fix that before anything else.

Map what you rely on

List your devices, servers, hosting, applications, network equipment, DNS, phone systems and the suppliers behind them, with a responsible contact for each. Good IT documentation makes this faster, and a gap in it is worth finding before you switch IT providers. If your records are thin, an IT assessment can establish what is in place.

Agree feasibility with the incoming provider

Share what you have found with the incoming provider. Agree that the handover is workable, with a planned start date and the scope of onboarding confirmed in writing. Then give notice to the outgoing provider.

Tell staff early

Let staff know you plan to switch IT providers, how to get help from the new provider and when any scheduled work will happen. Telling them before go-live avoids confusion about who to call.

How do you switch IT providers step by step?

The steps below set out a controlled way to switch IT providers. The order matters: contract review comes before notice, and the handover is not complete until outgoing access has been removed and your business has accepted the result.

To switch IT providers safely, each step needs a named owner on your side as well as at each provider. A decision maker in your business should approve the plan, the cutover dates and the final acceptance.

Who is responsible during the handover?

When you switch IT providers, responsibility needs to be clear at every stage. Two providers with access does not, by itself, settle who owns a problem when something goes wrong.

Why might the providers overlap?

A short overlap can give the incoming provider time to verify access, backups and monitoring while the outgoing provider remains available for agreed handover work. The length depends on the environment and contract. Both parties should know who leads support, who approves changes and who responds to an incident. Overlap should not leave two providers making conflicting changes.

Not every system needs to run twice. Some management, backup and security tools can conflict when two are installed together, so replacing them needs a controlled sequence. The objective is continuous support and protection with clear ownership, not unrestricted parallel administration.

What should be agreed for each service?

• Named lead. One person at each provider who coordinates the handover.
• Support owner. Which provider handles staff requests for each service, from which date.
• Monitoring and incidents. Who receives alerts and who responds to an incident.
• Change approval. Who approves changes, and who in your business signs them off.
• Escalation. The route to follow if something goes wrong or the providers disagree.
• Access and end date. The access each party needs, and when that access ends.

The joint advisory on protecting against cyber threats to managed service providers and their customers, hosted by New Zealand’s National Cyber Security Centre, recommends that contracts define security responsibilities, that providers apply least privilege and multi-factor authentication to their accounts, and that provider accounts are disabled once the provider no longer manages the systems. Those principles apply directly when you switch IT providers.

What does the business keep, and what does the provider manage?

The incoming provider takes on management responsibility for the systems it supports. It does not acquire ownership of them. Your business should keep control of its tenant, domain, data and recovery arrangements before, during and after you switch IT providers. Equally, not every licence, leased device or platform tool used by the outgoing provider becomes the customer’s property when the agreement ends.

List each subscription with its account holder, billing provider, renewal date, commitment, transfer conditions and the action required. Identify leased and supplier-owned items so they can be returned, bought out or replaced as agreed.

Share credentials through an approved secure method, such as a password manager your business controls. Set up named administrator accounts with MFA rather than circulating passwords by email.

Does Microsoft 365 need moving when you switch IT providers?

Not necessarily. Changing who administers Microsoft 365 and changing who bills the licences are separate tasks. A new provider can take over administration of your existing tenant while staff keep their accounts, mailboxes and files.

If your licences are bought through the outgoing provider under the Microsoft Cloud Solution Provider programme, Microsoft’s guidance on transferring subscriptions between partners explains that the incoming partner starts the transfer and the outgoing partner must approve it. Where a reseller buys through a distributor, that distributor is also involved. Annual commitments are not transferred or cancelled automatically because you switch IT providers, so check the terms before planning the move.

Removing partner access

At the agreed close-out, review delegated partner permissions in Microsoft 365 as well as named accounts, remote tools, VPN access and application permissions. Microsoft’s guidance on ending a GDAP relationship explains that this removes the partner’s granular admin privileges. It does not remove every other permission.

Microsoft also notes that removing a partner’s roles does not end the partner relationship, for example where that partner is still your reseller. Rotate shared secrets the outgoing provider knew, such as service account passwords and Wi-Fi keys, where required.

How do you protect backups during the handover?

Backups need particular care when you switch IT providers, because a handover can change who runs them, which tool runs them and where they are stored. Our guide to data backup strategy covers the wider planning.

• Coverage. Confirm backups include every affected system, including Microsoft 365 data, servers and business applications.
• Recovery point. Check the backups meet your recovery point objective, the amount of data loss the business can accept.
• Representative restore tests. Test recovery of a representative sample, including a whole system where relevant. One successful file restore does not validate recovery of the whole environment.
• Dependencies. Confirm that credentials, encryption keys and restoration destinations are available to the incoming provider and to your business.
• Retention. Keep existing backups through the agreed transition and retention period, not simply until go-live.
• Historic backups. Confirm how older backups can be accessed, retained or restored. Backup formats and provider platforms may limit portability.

Your recovery time objective is the target for how quickly a system must be restored. Ask the incoming provider how both targets would be met for your business, rather than relying on a general statement about its own restore testing.

How long does it take to switch IT providers?

There is no single timeframe to switch IT providers. Agree a date after discovery, once the incoming provider understands your environment. Each of these factors can determine the schedule.

• Contract notice. The notice period and any minimum term with the outgoing provider.
• Access. How quickly business-controlled administrator access can be confirmed or recovered.
• Licence transfers. Whether subscriptions move between partners, and the approvals involved.
• Hosting dependencies. Systems hosted by the outgoing provider that need a separate plan.
• Technical changes. Tool replacements or configuration work that needs a maintenance window.
• Supplier availability. Third parties, such as software vendors or phone providers, who need to take part.

A support-only handover for an environment that stays in place involves less work than one combined with a hosting move or tool replacement. Ask for a plan that separates the two.

What does it cost to switch IT providers?

When you budget to switch IT providers, separate one-off transition work from the ongoing support fee. These are the costs that can apply.

• Onboarding. The incoming provider’s work to take over support, document the environment and set up monitoring.
• Exit assistance. Handover work by the outgoing provider, where the agreement charges for it.
• Overlapping support. Any period in which both providers are paid.
• Licences. Remaining commitments, or changes when subscriptions move to a new partner.
• Tool replacement. New backup, security or management tools where the outgoing provider’s tools stay with it.
• Migration projects. Moving hosting, data or services to a new platform.

At Exodesk, standard onboarding is included in our support agreement. Migration projects are quoted separately once the scope is agreed. Exit assistance, overlapping support and licence changes depend on your agreements with the outgoing provider and suppliers.

When is it time to change IT providers?

A serious security failure can justify action on its own, without waiting for several problems to accumulate. For other concerns, evaluate the provider’s response against the business impact and the agreed service, rather than treating every slow routine request as equivalent.

Recurring faults deserve a closer look before you decide. They can have hardware, application or budget causes as well as service causes, so a pattern of repeat issues is a reason to review the cause with your provider rather than proof of poor service. If that review leaves the issues unresolved, it is useful evidence for the decision.

Other reasons to switch IT providers include a business that has outgrown its provider’s scope, a need for planning and IT strategy the current arrangement does not cover, or support that does not match how and where your staff work.

What should you ask a new IT provider?

• Scope. What support and onboarding include, and what is quoted separately.
• Access controls. How administrator access is granted, protected with MFA and reviewed.
• Responsibility. Who owns monitoring, incidents and changes once support starts.
• Escalation. The route for urgent issues and for concerns about the service.
• Recovery. How your recovery point and recovery time objectives would be met.
