Hello,
I need help, my predecessor has installed percona on one of your servers, but left no manual or whatsoever.
We have a centos 5.9 server (64bit) and need to update/upgrade mysql version. What is the best way to do this?
Update from 5.0 to 5.1.x or from 5.0 to 5.5.x straightaway?
And what are the right steps to do this? I read some articles, but they are all installations from mysqld to percona mysql version.
Preferably our downtime must be as minimal as possible.
