I need to add the primary extension field for about 200 users into UCM 6.1.2. I have noticed that when importing the update users BAT file it asks for a user template. It seems that every user you want to update this way must have their PIN/Password reset in the user template even when you set these fields to be ignored in the csv file. Surely this is not necessary but I cannot see any way around it apart from deleting all my users and using the export all/import option. I don't really think it's a good idea to use this other option due to the fact that all these users are already logged in to EM.
Is anybody able to confirm that this is expected behaviour?
