The reason behind it is very simple, if you do a system upgrade and
suddenly have another BDB version on your box, or you move the mailstore
from an older cyrus-imapd server to a newer one, you'll have the BDB-fun
discussed on this list very frequently (it's not only with cyrus-imapd,
just ask those openldap or subversion users...). Now, the Invoca rpm
package solved this by bringing the cyrus-imapd messagestore to a portable
state whenever it's not running - and by switching all berkeley databases
to skiplist by default, those problems are gone for most users anyway.
Another benefit is that you can stop cyrus-imapd, change the database
configurations and start it up again. All will convert automagically.

However, you are not using the Invoca rpm so I don't know exactly how it
works in your situation (the packages shipped by RedHat/Fedora are based
on older and modified versions of the Invoca rpm).
