Can You Edit a Saved SharePoint Migration Tool Session?
Question details
The user wants to know how to modify a saved session in the SharePoint Migration Tool (SPMT) to exclude additional file types or extensions.

- Product
- SharePoint Migration Tool
- Device & OS
- not provided
- Scenario
- Attempting to update the file exclusion parameters of a migration session that has already been saved in SPMT.
- Observed behavior
- Saved sessions only provide options to 'Run incremental' and 'Delete', lacking any built-in functionality to edit configurations or add new excluded file types.
Review your current migration requirements and compile a complete list of all the specific file types or extensions you need to exclude before proceeding.
Create a New Migration Session with Updated Exclusions
Since the SharePoint Migration Tool does not support editing an existing session, the official workaround is to configure a brand new session with your updated file exclusion rules.
Microsoft currently does not provide a built-in feature to modify the core configuration of a saved migration session in SPMT. Saved sessions are limited to basic actions like running incremental updates or deleting the session entirely.
Open the SharePoint Migration Tool, locate the saved session that lacks your desired exclusions, and select 'Delete' to prevent future confusion.
Click the 'Start a new migration' button on the main dashboard to begin configuring a fresh migration task.
Progress through the setup steps until you reach the settings and filters section. Carefully add all the new file types or extensions you wish to exclude from this migration.
Once your configuration is complete, save the new session parameters and run the migration.
