I have MySQL community version 5.5.50 running in linux having 4-5 databases on it.
Requirement is to upgrade to Percona Server 5.6.31-77.0.
What are the pre-requisites that I need to check before upgrading? Are there any common errors that i'm likely to face?
I'm simply planning to backup the databases. Remove the MySQL binaries. Install the new Percona Server and restore the databases.
