Re: [Marketing Mail] [Caution: Message contains Redirect URL content] Re: Migration from 2.5 to 3.4

Can you use the procedure described in section 6 on page 
https://www.cyrusimap.org/imap/download/upgrade.html#backup-and-copy-existing-data 
of the upgrade guide?

It is for the mail databases but assume it will work on cyrus-sasl 
databases too?

You need to run the database conversion (cvt_cyrusdb) on a copy of the 
database on the old server before you copy it to the new server, because 
the new one doesn't know how to deal with berkeley database files to do 
the conversion. There is a man page for cvt_cyrusdb on the website, and 
it should be installed on the server.
