Safely Transition Licensing from IONOS to a New CSP

The standard procedure to migrate licensing relationships without data loss by coordinating with both IONOS and your new provider.

Transitioning your licensing involves removing IONOS's partner privileges and assigning licenses from your new CSP. It is crucial not to delete users or revoke licenses before the new ones are ready, as this can cause data loss or service interruptions.

Contact IONOS Support

Reach out to IONOS and formally request the removal of their delegated administration (or GDAP access) and to end the licensing relationship.

Document the consequences

Confirm with IONOS that removing the partner relationship will not immediately delete your tenant data, domains, or user accounts.

Authorize the new CSP

Your new Cloud Solution Provider will send you an authorization link. Open this link, sign in to the Microsoft 365 Admin Center with your Global Admin credentials, and accept the relationship request.

Purchase and assign replacement licenses

Once the new CSP relationship is established, purchase the necessary Microsoft 365 licenses through them. Immediately assign these new licenses to your users in the Admin Center under 'Billing' > 'Licenses'.

Verify configurations

Double-check your domains, DNS settings, and user access to ensure everything transitioned smoothly and services remain active.

Safely Transition Licensing from IONOS to a New CSP

Avoid Disruption: Always ensure your new CSP licenses are active and assigned to your users before the original IONOS licenses expire or are revoked.

Frequently Asked Questions

Will I lose my data when moving from IONOS to another CSP?

No, your data is tied directly to your Microsoft 365 tenant, not your Cloud Solution Provider. As long as you do not delete the tenant or individual user accounts during the transition, your emails, files, and configurations will remain completely intact.

Do I need to create a new Microsoft 365 tenant to change CSPs?

No, creating a new tenant is not required. You simply need to authorize your new partner (CSP) to provide licenses for your existing tenant and subsequently remove the old partner's administrative access.

Is there any downtime during the license migration?

There should be no downtime if the transition is coordinated correctly. By ensuring the new CSP licenses are purchased and assigned to your users before the old IONOS licenses are removed, users will experience continuous, uninterrupted service.

How do I accept a relationship request from a new CSP?

Your new CSP will provide an authorization link via email. You must click the link, log into your Microsoft 365 Admin Center using your Global Administrator credentials, and approve their request for delegated administration privileges.
