You can decide to add or remove administrators using the Microsoft 365 group owners field. Note that you must have at least one valid administrator and can add as many as SharePoint allows you to.
Note: When promoting with the modern Team site template (Microsoft 365 Group) the default administrator list will include administrators from the parent site collection and the site owners of the subsite.
Select what you want to do with the original subsite.
- Keep original subsite as is - Promote the subsite as a new site collection, and keep the original.
- Delete the subsite after a successful promote process - Promote the subsite as a new site collection and delete the original subsite after it's been copied. If any error exists in the subsite or if the Promote job is canceled, the delete operation will not occur.
