Change all users from one Domain to another Domain

[malcolmhum]

Hi

We are going through a re-brand and are looking to change all users that have email addresses in one domain over to a new one. What is the best way to do this?
I can see potentialy just editing and renaming the existing domain would work, but I also want to alias the old domain onto the new one so we don't miss any emails.

Regards

You can either:

1) Rename the existing standard domain to move all users to the new domain with the same settings then create the old domain again as an alias domain to the new one
2) Create the new standard domain, then in the admin dialog interface users page filter to just that domain's users using the drop downs then use the Move button to move all users over to the new domain. Then change the old domain to an alias domain.

(1) is probably easier. However, renaming a domain may keep the old file path (which you can edit of course). (2) is probably the better way of doing it but either works fine.
