Re: Upgrading slave from 5.0 to 5.1 - replication errors

Mostly, upgrades simply work. But, because of improvements/fixes/etc, there are a lot of "watch-outs".

0. in my.cnf / my.ini, set it so that the slave will not automatically start
1. Stop mysqld
2. Upgrade to new version
3. run mysql_upgrade
4. START SLAVE

Steps 0 and 4 are to give you a chance to run step 3.

Performing a backup (before or after step 1) is a safety measure.
