Upgrading to Dovecot2 would allow you to solve this in
various ways:

 	- use "doveadm force-resync"
 	- user director to bind to a particular server

You could put the indices on a shared filesystem.

If neither an update nor shared indices are feasible, maybe you can
enable the master user feature, and run a script that logs in as each user
and do an IMAP operation that will force a resync of the INBOX indices.
For example,

 	# On IMAP server with a localhost interface
 	for u in $users; do
 		echo "1 login $u*master masterpw\n2 SELECT INBOX\n3 logout" | \
 		nc 127.0.0.1 143
 	done
