Yes, it is, if you first grant the admin account all rights to all
mailboxes, which is kind of a pain. My preferred approach, if you can
afford to have the mailstore off line for the duration, is to simply
bulk-change the passwords to some known value prior to commencing the
transfer. For example, if you are using unix system passwords, change
the /etc/shadow (or whatever) file. If you are using LDAP change the
userPassword attributes, etc. You can stash away a copy of the
originals and restore them later.
Then I would run a script, written in your favorite scripting language,
to walk through a list of users and initiate the transfers. You can run
multiple transfers at once, just keep an eye on your I/O loads to make
sure you aren't just loading down the systems too much.
Cheers,
