Because of the increasing number of businesses using Microsoft Office 365, we receive many requests for migrating between Office 365 Tenants. This can be triggered by an acquisition or merger event.

Types of migrations like this typically involve migrating from one O365 Tenant to another, existing O365 Tenant. Careful planning is required for migrations like this. Microsoft provide some new Tenant to Tenant migration tools for the data migration aspects, but this does not reflect all the complexities involved.

O365 provides many services other than Exchange Online, these services need to be considered. There may be Active Directory involved, with multiple local Active Directories.  Is Single Sign On being used?   Anyone using Teams?  Any SharePoint data?   How can an email domain be registered on both Tenants?  What level of coexistence can be established?

Migrating between O365 Tenants is one of the most complicated processes  you can undertake, due to the many dependencies involved, and with production users on each Tenant, extra care must be taken when making each technical change.

One constraint to consider is that any domain name cannot be registered in more than one Office 365 Tenant.

If the O365 Tenant to Tenant migration is driven by a merger or acquisition, then legal dates will likely be involved, this adds extra pressure to any work required. planning these types of migrations as early as possible is strongly recommended.
