The main problem is that the convert script says to install db4.2-util, but it is not available in squeeze. I assume it's in Lenny, but don't know if the version there will work on a squeeze system.
Some other issues, in chronological order: 1. I had some trouble retrieving the file; wget http://anonscm.debian.org/gitweb/?p=pkg-cyrus-imapd/cyrus-imapd-2.4.git;a=blob;f=debian/cyrus-upgrade-db got me a web page. lynx on the same URL got me the general repository, not cyrus-upgrade-db. I ended up navigating to it through the tree link. Maybe the right way to do this would be obvious if I knew git. 2. When I ran the script it said /bin/bash: db4.2-util not installed /bin/bash: please do: [sudo] apt-get install db4.2-util package /bin/bash: and rerun the upgrade again /bin/bash: db4.7-util not installed /bin/bash: please do: [sudo] apt-get install db4.7-util package /bin/bash: and rerun the upgrade again I did apt-get install db4.2-util db4.7-util but I think someone might copy the instructions literally and type apt-get install db4.2-util package. I suggest removing "package" from the message (unless this is some syntax I'm unaware of). As indicated above, db4.2-util is unavailable. 3. Is db4.2-util actually necessary to upgrade? Looking at the code, it appears this is used to checkpoint the database before the main operations. Is that necessary if cyrus is already shutdown normally, as I thought it had to be before the upgrade? 4. The script works with berkeley-nosync as well as berkeley, right? 5. I'm not sure, based on a quick read, if the script backs up the entire mail spool. If it does, it would be good to make this optional since it can take a lot of time and space, and the admin may have already made backups. 6. I've seen some suggestions (not Debian-specific, and possibly old) that there were files that needed to be upgraded on a per user, or maybe even per folder, basis. The code doesn't appear to do that. Any problems there? 7. It might be useful to note the script should be run as root. I wondered if it should be run as cyrus until I saw the code has su cyrus at strategic points.
