upgrade problem 2.0.16 Berkeley DB 3 to 2.2.12 Berkeley DB 4

[Pascal Mouret]

I was just thinking : Couldn't it be that ctl_mboxlist -u already 
created the new mailboxes.db as skiplist ?
I mean, as far as I have understood it, ctl_mboxlist -u creates the 
mailboxes.db using the backend defined in /etc/imapd.conf, that is 
skiplist if you did not state anything, berkeley if you added a line like :
mboxlist_db: berkeley
Maybe the problem lies there
Hope this helps

By the way, does anyone know if there are other databases to upgrade 
when moving from BDB 3 to BDB 4 ? I am not quite sure about some stuff 
that's in /var/imap, such as /var/imap/db. Do I have to upgrade it ? or 
is it not very important, in which case I can delete it and start from 
scratch.
Thank you very much
