I recently completed a migration and upgrade of our Laserfiche server/DB. This process also was a move from one domain to another. There are about 75 local users manually added to the server, a vast majority are no longer with the company any longer. There is an ADMIN user that I am obviously going to keep as well as our VAR's login, which I am going to keep for any needed support in the future. 

Now, this system is no longer an actively used system and is only being used for archival purposes - to keep due to SARBOX and other regulations. It may honestly never be needed, but we have to keep it, of course. 

Standard policy is to manage permissions via Windows Security Groups. I believe I understand how to work that out as it is pretty straightforward. However, I would like to delete all of the outdated user accounts that are present. Will this cause any problems at all? 

Finally, there are some legacy DB users that seemed to be added during the upgrade of the DB - can I safely delete these also since they are for the old database, since deleted, and are for a different domain altogether. 

Thanks!

Mike
