I'm running MySQL 5.0 in production on CentOS. How do I migrate to Percona Server 5.1 safely?

The documentation of Percona Server doesn't include any information on migrating. Any help is greatly appreciated.

At a guess I'd say mysqldump your database from MySQL and reimport it into the Percona server.

I don't know if you can just fire up Percona server pointed to the same datadir as MySQL. Might be worth investigating.

You can just install Percona Server over MySQL. It is binary compatible. – Aaron Brown Jan 29 '12 at 22:17

The data files are compatible with percona server. You just need to start percona server mysqld and everything will work.

Only when you enable some features (like extra rollback segments) on percona server, you might not be able to go back to mysql. but you rarely need to change this parameter.

Here is a good tutorial You need just remove mysql-server and install percona-server, that's all.

Percona and Mysql binary compatible!

apt-get remove mysql-server mysql-client mysql-common
apt-get autoremove

Than just add percona repo and

apt-get update
apt-get install percona-server-server

After that you can start Mysql and it will work

service mysql start

It's pretty much the same upgrade path from 5.0 to 5.1, of course to make better use of Percona enhancements you should consult the wiki.
