Yes — WipeAway is designed for exactly this use case. It removes historical or duplicate events after migration while leaving the calendar structure and sharing permissions intact.
Post-migration calendar clean-up is one of the most common use cases for WipeAway. After a Workspace migration, shared calendars often contain years of historical data that migrated unnecessarily, duplicate events from the migration overlap period, or entries associated with accounts that no longer exist in the new domain.
WipeAway lets IT administrators select affected calendars, set a cut-off date, and remove the unwanted events in a single controlled operation — without affecting the calendar's sharing configuration or any integrated tools.
