True or false? It can be difficult to rollback or reverse a data migration if records are merged or updates are made to properties of existing data during the import.

While HubSpot has standard rollback tools (like deleting newly created records or using the "Backup & Restore" menu to revert mass property changes), reversing a migration becomes significantly more complex if existing data was modified or records were merged. This is because a basic file deletion will not restore overwritten historical values, and records that have been merged combine separate timelines and data structures into a single record ID, making it highly difficult to cleanly unravel the data back to its original state without relying on manual entry or historical property exports.
