I used the Invoca srpms from Simon Matter and built them for Redhat 5
and upgraded from the 2.3.x version supplied with Redhat. All of the
databases update in place (new version uses all skiplist instead of
some skiplist and some Berkeley DB). The only thing you need to look
out for is that when users access their mailboxes for the first time
after the upgrade, their indexes are updated. If you have several of
these go off at once, it can send your load up quite high. Thus, if
there is any way to stagger this, it can be helpful--especially if you
have lots of mailboxes.
