i have a client who needs to migrate from one domain to another, and i
want to be sure to make the switch in the least disruptive way.

they're running cgp 4.2.10 on os x 10.3.9.

they have three (3) domains configured, with the majority of user
accounts in the secondary domain.

the primary domain is and has been active, but they haven't used it as
such for awhile.

the third domain isn't used and will go away soon.

i'll refer to the domains as:


they want to continue receiving mail addressed to but use for all

on a whim, i tried creating an account under the secondary, tarring
the account data, deleting the account, and moving to the primary
domain and restarting mail services, but that didn't work.

Did you delete the secondary domain and then make it an alias of the primary domain?

do i need to re-enter license keys in this situation?

Not unless you are changing the primary domain name, eg from to

what's the best way to accomplish this task, and how much downtime
would you estimate?


Depends how many users you have. It also depends how your users are setup. If they are all on POP3 and you only have 20 users, then deleting and recreating the users won't take long. If they use IMAP or MAPI and you have a lot of users then use a imapmovemail type of script. It may take longer. Once you have moved the users then delete the secondary domain and make an alias of the primary domain.

thanks for your help.
