With the migration report, you can clear your history. It is important to understand that every object migrated with Sharegate is saved in the log file. After some time, this log can become very large and filtered requests can become slower. In those cases, it might be a good idea to delete the records that are no longer needed.
To do so :
- Select the sessions you want to delete
- Click on Clear Sessions.
- Confirm that you want to delete all the entries in the selected sessions.
