We have at the moment three primaries (ZCM 2017 upd 1) in our zone, two of which are old running on SLES and upgraded several times. For several reasons we'd like to delete these one at a time and eventually replace them with appliances. Which are the major pitfalls when deleting a ZENWorks primary? We use an internal CA and we have moved it away from the server we plan to delete first. All clients are pointed to one of the servers not to be deleted.
Anything else to do before going to action?

Kind regards
