Cross-Tenant Migration in Microsoft 365 - Generic Overview


User Adoption Process Cross Tenant Migration

  Cross Tenant User Adoption Process   Change & Adoption is the most critical task in any tenant-2-tenant migration. Not only users who are migrated are impacted heavily by the migration. Users in the target tenant too. Especially in the target tenant they will experience constant changes. New users and groups are appearing, but not “life”, not actively working in the tenant. Further, new services related content will sequentially appear, like SPO sites, Teams Channel, Yammer or others. Since data is flying in slowly, there must be a communication and identification in place, that user are enabled identifying data source in migration. Same applies, for user in the source environment. Content/ data migrated will be in read-only. Content could become unavailable due to accomplished migration to the target. All depends on the migration process, procedures and planning. This needs to be communicated to all users in proper manner. Talking about external users, there is even a m

Teams Personal Chat Migration into Azure Data Lake

  Personal Chat Migration into Azure Data Lake   Another approach, rudimentary described in the white paper is, migration or better said exporting Teams chat messages into Azure Data Lake solution.   To be said upfront, this is not a solution you or a consultancy company can do, rather you must engage Microsoft (MCS/PSS). This is an internal Microsoft solution using a private API for export.   There are several options on how data can be extracted: -           Single large XML file -           Individual XML files per Teams user There is no other way yet, rather than using XML. Further, you must purchase an Azure VM and Azure Storage. The costs aren’t too high and acceptable. After Chat message extraction, the consolidated XML file will be sent via email or copied into OneDrive.   Talking about user experience. This is not a user-friendly option! As user must have an XML reader and message can only be found by an XML search. This makes it difficult finding messag

Cross Tenant User Migration Approach and considerations

  Cross Tenant User Migration Approach and considerations In any Tenant 2 Tenant migration the migration approach you have to consider based on: ·        Migration Tools ·        Communication/ Work clusters ·        User and shared data The combination and dependencies of the above will guide you to the best possible decision, how you migrated a tenant and merge it into the target environment. Migration of data is time consuming. We explained the tenant limitation (throttling) in a chapter above. Nevertheless, pre-loading of data into the target tenant is crucial including the sequence required for planning.   Migration Tools There are multiple vendors on the market providing tools, tool sets. They either run on-premises, in Azure or have developed their own cloud-based solution. Principally you will consider a mix of different tools and vendor. Most companies run a hybrid environment. This is in most cases for the users and groups synced between the on-premises Ac

Meeting Link Migration for Teams in Cross Tenant

  Meeting Link Migration for Teams Note: both, first user Mailbox/Calendar and Teams must be migrated A 3 rd party tool is required to accomplish a meeting link migration. With Exchange Mailbox migration, all items, including calendar item will be migrated as they are. Calendar item with a link to a Microsoft Team meeting link back to the original Team meeting in the source tenant. The URL is retained. A Teams Channel meeting is not recreated in the target tenant. Those meetings must be rescheduled manually by the channel owner.   How it works (e.g. Quest): The meeting link migration task will create a new Team meeting with the original meeting details in the target tenant. It will set the target user as the organizer. The original meeting migrated to the target will be canceled. The cancellation will be automatically sent out to the organizer and recipients. Meeting Link Migration Considerations Before migrating Teams meetings and their respective link, be aware of the

Example of our cross tenant user data migration approach

  Example of our user data migration approach: Important is the completion of your data pre-load for OneDrive and Exchange. Remember, that the pre-load should include as much data as possible. Syncing on the cut-over day data > 10 GB or more than 500 files in OneDrive, might end up with an INCOMPLETE set of data in the target. Therefore, you should urge using the OneDrive Cross-tenant OneDrive Migration tool from Microsoft. The user will than see data being migrated (missing data) upon he starts working in the target environment. This will not be happening with the cross-tenant migration tool. The switch to the target tenant will take approx. 15min. Migration of Teams personal Chat messages, we mostly limit to 15 days. The performance is acceptable migrating approx. 400 – 800 users/day. Note: You should have special procedures in place for legal-hold users, white glove and user object facing issues. Prepare source and target tenant and ensure the readiness for Microsoft too
