How to migrate backup data between repositories for Veeam Backup for Microsoft Office 365

The script performs the following operations:

1. Select Organization. Defines the organization associated with the data to be migrated.
2. Select Backup Proxy. Defines the backup proxy server that hosts existing backup data.
3. Select Target Repository. Defines the target object storage repository.
4. Limit Migrations Sessions. This step configures the maximum number of simultaneous migration sessions to half of all threads configured for the selected backup proxy server. For example, if there are 64 threads configured on the backup proxy server, it will limit the number of migration sessions to 32 concurrent migration sessions.
5. Disable All Jobs for Selected Organization. Disables all backup jobs created for the specified organization.
6. Create a List of Source Repositories. Creates a list of backup repositories used by the backup jobs from Step 5 that will be used as source repositories. (If a repository is not in use by at least one backup job, the data residing there will not be migrated.)
7. Get and Migrate All Users. Creates a list of all Users, Sites, Teams, and Groups located in the repositories from Step 6 and then migrates their data.
8. Reconfigure Jobs to Use New Repository. Reconfigures all the jobs from Step 5 to use the object storage repository that is defined as a target repository and enables all jobs disabled at Step 5.
