In two weeks, we are going to phase out a Unix system which I will call "x". The 1200 or so users of that system will all be migrated to a much larger and faster system called "y". The userid will be the same for system "x" users on system "y". Some of these people using system "x" are Listserv subscribers and/or list owners For mail purposes and other issues, the users will be able to access their email and log into system "y" by referring to the system "x" hostname after the migration thanks to some DNS changes and some mods to the configuration on system "y". What I am wondering about is if I make an entry in the aliases.names file on Listserv such as: :nick.Y :alias.X will it enable system "x" users to access Listserv via the Web GUI without them having to change their Listserv password, alter the subscriptions, and/or any list's "Owner" keyword? The idea is to try to make this migration as seemless as possible for the users of system "x". I am pretty sure this would work, but I want to confirm first. I also am aware of issues such as people maintaining and/or being subscribed to Majordomo and other types of lists outside of our control. That, I do not see any way we can help the users in this transition. If anyone has any comments on this issue, please let me know. Thanks
