Details
Due to technical limitations of the Azure Migration API or ShareGate Server extension, some files or list items cannot be migrated using Insane mode. The complete list of limitations for Insane mode can be found in the article, Migration using Insane mode with Microsoft 365 and on-premises.
When ShareGate Migrate detects an item that cannot be migrated using Insane mode, it automatically switches to Normal mode for all the items in that library. Normal mode is subject to some limitations when migrating to a Microsoft 365 environment. For more information, see Normal mode.
