Go through the spaces in Data Science and see which spaces are not owned but a current member of the team
Assigned those spaces to members of the team according to their knowledge of each page
Each team member will go and check those pages and decide which ones should be kept.
Pages that the team member doesn´t consider should be kept, will be revised by a supervisor to make sure that those pages are obsolete and can be archived.
When a page is Archived with Content Archiving, that page will be hidden from any search and from its original space, but it still could be accessed by an administrator.
Archived pages need to be revised after a year and decide if we keep them there or it is time to delete them.
