Currently, if the customers use CMAC to test spaces migration, for the final migration on the same site, they will need to either manually delete the spaces or to use the REST api call: https://developer.atlassian.com/cloud/confluence/rest/#api-space-spaceKey-delete, because the spaces will not be overwritten and a new plan for the same space will fail

Would be nice to have for CMAC to have an option to delete the space instead of failing the plan, and once space is deleted the plan could continue implemented in CMAC.
