Re: how to convert db4 mailboxes.db to db3 ?

[Patrick Morris]

Even if it's db4, you need to pass "db3" as the database type parameter:

# ./cvt_cyrusdb mailboxes.db db3 mailboxes.skiplist skiplist

Patrick,

  I have tried to do the conversion from db4 to skiplist for the
cyrus-imap
compiled with db4, but, there is a error message:
# ./cvt_cyrusdb mailboxes.db db4 mailboxes.skiplist skilist
fatal error: unknown old backend
Why doesnt it recognize db4? I have to compile with some other parameter,
like
--with-mboxlist-db=db4 ?
Thanks

Sandra

I'd assume this is because you're moving from a system that uses db4 to
one using db3.  If that's the case, the easiest thing to do is to
convert them on the first system to a format both recognize (such as
skiplist).  Then, convert the skiplist version back to db3 on the other
system.

I want to know how I can convert the files .db cyrus uses to db3!

Thanks a lot.
