Current modernization engine has the switch KeepPageCreationModificationInformation, but it does not work perfectly if the existing modifier/creator no longer works at the organization and his/her account has been deleted from the directory. In this case, the engine sets the modified/created time stamps to now and replaces the modified by/created by information by the user who is running the modernization. Hopefully this issue will be fixed in the new engine. Few ideas:
- keep original modified/created timestamps regardless
- Allow setting specific account if existing user does not exist
- Allow setting only timestamps
