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

I was trying the same procedure here : upgrade problem 2.0.16 Berkeley DB 3 to 2.2.12 Berkeley DB 4

I have used the ctl_mboxlist -d to dump the old db3 mailboxes.db file , on the old machine . After a copy to the new machine with 2.2.12 Berkeley DB 4, I did a ctl_mboxlist -u., and a new mailboxes.db was created.
It was ok, running perfect.

But I would like to convert Berkeley DB do skiplist, and when I did the following, there was a problem :

./cvt_cyrusdb /cyrus/imap/mailboxes.db berkeley-nosync /cyrus/imap/mailboxes.db.new skiplist Converting from /cyrus/imap/mailboxes.db (berkeley-nosync) to /cyrus/imap/mailboxes.db.new (skiplist)
fatal error: can't open old database  <<<<

Could anybody help me? If its working with DB4 why it can't  read it?

Thanks - Sandra

Has anybody got an idea ? Where did I go wrong ? Could it be a result of
running version 2.2.12 cvt_cyrusdb while 2.0.16 is still up ?



Running two different versions (or even having them present on the
system) of BDB libraries is always somewhat a problem. Save yourself
a lot of trouble and use Cyrus' utilities to dump the mailbox database
into a text file (ctl_mboxlist -d) on the old system, then read the
database back with ctl_mboxlist -u on the new installation.

cvt_cyrusdb is used to convert between two different Cyrus database
backends, not to upgrade a Berkeley database.
