Yammer tenant-to-tenant migration is the process of transferring Yammer network data from one Yammer network (tenant) to another. This might be necessary in situations such as company mergers, acquisitions, or divestitures, where two separate Yammer networks need to be combined or separated.

Yammer tenant-to-tenant migration is different from migrating Yammer data to another platform or application, such as moving Yammer data to a different social network or collaboration tool. Tenant-to-tenant migration specifically involves transferring data between two Office 365 tenants while preserving the existing Yammer network structure and features. During the migration process, all data within the Yammer network, including users, groups, messages, files, and other Yammer content, is transferred from the source tenant to the target tenant. The migration process can be complex and may require careful planning and execution to ensure a smooth transition with minimal disruption to users.
Before starting a Yammer tenant-to-tenant migration, there are several prerequisites that need to be met to ensure a smooth and successful migration. Here are some of the most important prerequisites to consider:
The Yammer tenant-to-tenant migration steps may vary depending on the specific requirements of the migration. Here are some general steps involved in a Yammer tenant-to-tenant migration:
Step 1. Plan the migration
It is important to understand the structure, usage, and content of both Yammer networks to determine the scope of the migration and any potential issues that may arise. Determine the migration approach, identify the migration tools that will be used, and create a detailed migration plan that includes timelines, responsibilities, and contingency plans.
Step 2. Prepare the source and the target Yammer network
This involves taking steps to ensure that the source Yammer network is ready for migration and the target Yammer network is ready to receive data from the source Yammer network. This may include disabling the automatic provisioning of users, cleaning up data, and making necessary changes to user permissions.
Step 3. Perform the migration
Use migration tools to transfer Yammer network data from the source network to the target network. This may include transferring user accounts, groups, messages, files, and other Yammer content.
Step 4. Verify the migration
After the data transfer is complete, verify that all data has been successfully migrated and is accessible in the target Yammer network. Communicate with users about the migration and provide training and support as needed to ensure a smooth transition.
Yammer tenant-to-tenant migration can cause several potential challenges and common issues that can arise. Here are some of the most common challenges and issues you may encounter during a Yammer tenant-to-tenant migration:
Compatibility issues. The source and target Yammer networks may have different configurations, which can result in compatibility issues during the migration process.
Data loss or corruption. If data is not migrated properly or is corrupted during the transfer, it can result in data loss or corruption, which can cause issues in the target Yammer network.
Third-Party Integrations. If the Yammer network includes third-party integrations, these may need to be reconfigured or may not be compatible with the target Yammer network.
Downtime and Service Disruptions. Users may experience disruption or changes to their workflows during the migration process, which can impact user adoption and overall productivity. DNS or email changes associated with the migration can result in temporary email delivery issues or other disruptions that can affect user experience.
User Training and Communication. Insufficient communication and training to users can lead to confusion and frustration during the migration process.
To mitigate these challenges and issues, it is important to plan and prepare thoroughly, engage with Yammer experts and third-party migration services, and communicate effectively with users throughout the migration process. It is also recommended to conduct testing and validation before, during, and after the migration to ensure a successful and smooth transition.
