Cross-Tenant Comparison (Tenant to Tenant)

 The main head word in T2T comparison is the “Technology Harmonization”. Beside this, users will experience a different M365 feature usability, this is the other side to be identified and leads to the Change & Adoption approach.


Technology – what is different between source and target

Several topics are included in this topic, not limited to technology only but overlap with user experience too.

Commonly we start with the licensing comparison. This might mainly restrict the usage of services or limit the services towards migrated users. From here you analyze each service step-by-step. Not only data / storage limitation could apply. Like in personal OneDrive, where the target could have lower storage limits than in source.

Areas like Guest User Access, Domain restrictions, Teams federation and other B2B configurations might lead to data migration/ usage limitations. It is advised to work with both side equally and see how the target environment is leading and if changes must apply, how this governance can be achieved.

Users can work quite freely in a M365 tenant, like they can create new services attached to M365 groups. This is could be different in the target tenant. Not only this is a technical restriction, but also impact the user experience intensely.

The most complex task for comparison is the AIP, labeling, policies and encryption. Matching both sides is a project in itself. Encryption is another hassle, as the AIP encryption keys must be accessible from the target and must be migrated while you migrated the DNS domains. IF DNS domains aren’t migrated, it must be considered another project in a project, decrypting source data and re-encryption during migration.


User Experience – what changes imply for users


Migrating user experience from source to target is completely depending on the possibilities and feature sets in the target environment. As an experience isn’t technical, rather than it is behavioral.

Work and human culture in the target environment might also differ from source. Only a holistic approach will make users feel comfortable after the migration.

Compare the technical feature set per service and list the difference between source and target. Go on with conducting interviews with the IT departments and users across the company.
You should involve two skills, the technical expertise and a good adoption specialist. Both need working hand in hand with the client.

The result will directly define the areas where the change & adoption team will work on.
