Most of the important stuff is clearing any held packages, and fixing broken ones, so you have a standard Squeeze installation to start from. You also need to make separate provision for any software not installed using the apt tools e.g. from source, or using a proprietary installer. Always do a full OS backup before upgrading. It's easy enough to backup the MySQL data separately, and restore it to another installation if necessary. Probably also take a separate backup of /var/www, and /etc, just in case of problems arising from Murphy's Law. If you're running a production server, you probably know the data and configuration information you would need if you have to rebuild onto a clean OS installation. I use Apache and MySQL, and there were no upgrade issues at all, but I use the standard Debian repository. If you are using different software from the Squeeze versions then you'll need to check the dependencies and confirm that Wheezy fulfils them. I use exim4, Courier and Sqirrelmail for email, so I can't advise there. -- Joe -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
