The premigration report is populated by running the following two types of task from the On Demand Migration (ODM) Power BI workload.
- Discover All Contents (is expected to populate Workspaces, Gateways, Semantic Models and Connections)
- Collect Statistics (is expected to populate Reports, Users and Object Roles)
The Discovery tasks on the Workspaces, Gateways and Connections also updates the premigration report.
Example of a populated report 
The premigration report will not be fully populated until Discover All Contents and Collect Statistics are processed.
Example where Collect Statistics has not been completed 
Example where Collect Statistics processed successfully 
In cases where the tab is not populated:
- Verify Discoveries have been run successfully
- If Discovers have completed, review the task and events for errors
Note: There may be instances where data is legitimately not available, such as an environment where Gateways are not used. This should be verified by reviewing the source tenant.
