upgrade problem 2.0.16 Berkeley DB 3 to 2.2.12 Berkeley DB 4

[Sandra]

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
