What do you mean by a "new domain" in this context?
The user's email addresses are changing from username@old.domain to username@new-domain.
That can be handled by address rewrites within the MTA.
Is the server changing?
No.
Is the storage changing?
The user's home directory is based on the user's email address, so this is changing.
In my setup, I have virtual users. So the home directory is in the /var/spool/virtual/$domain/$user/mdbox
How is yours setup? If the domain name changed, from domain1 to domain2, I believe it would be easy to change as follows:
cd /var/spool/virtual/ mv $domain1 $domain2
Well, it the size of $domain1 is in TBs, I'd probably do it another way as doing mv is a bit dangerous with very large datasets:
cd /var/spool/virtual
mkdir domain2
cd domain1
for d in ls -1; do mv $d domain2/$d; done [ or something closer]
In my thinking, a domain change is as simple as using a rewrite rule in your MTA.
Also the user's login-names needs to change from old to new domain, and all their data needs to move from old to new domain.
And the login names are stored in a flatfile or db?? Either way, you can do a rename. Dump the database and just use vi to rename old-domain to new-domain, then drop the db and import the dump.
mysqldump dbname dbname.sql
vi dbname.sql :g/old-domain/s//new-domain/g mysqladmin drop dbname mysqladmin create dbname mysql dbname < dbname.sql
You can also edit the flatfile to s/old-domain/new-domain/g cat flatfile | xargs sed -i.BAK 's/old-domain/new-domain/g'
Maybe I still don't understand you:-)
