Migration Assessment Scan: Custom Permission Level
In SharePoint, it is possible to create a custom permission level and then assign that permission level to users and groups. Some migration tools will have problems moving this information to SharePoint Online. As a result, permissions will not be the same for impacted users and groups post migration.
For more information on permission levels, see Understanding permission levels in SharePoint.
With some tooling, this data is not migrated. It is recommended to use the permission levels provided by SharePoint. However, if custom permission levels are required, the permission levels would need to be manually recreated on the SharePoint Online sites.
Any site that is configured as "No Access" (locked), in SharePoint will be skipped. To see a list of locked site collections see the Locked Sites scan output.
Preparing for Migration
Understand the custom permission levels in use in your source environment and determine the plan to move forward. Either move users and groups to the default SharePoint permission levels, or build out a plan for creating the custom permission levels and fixing permissions post migration.
Validate the users and groups have the correct permission levels. If you needed to create custom permission levels, ensure those are functioning as expected.
