When upgrading to MySQL Enterprise from Community Server you need only follow the installation process to install and upgrade the packages to the latest version provided by MySQL Enterprise. You will also need to install the latest MySQL Enterprise Service Pack and any outstanding MySQL Hot-fix packs.
Be aware, however, that you must take into account any of the changes when moving between major releases. You should also check the Release Notes for details on major changes between revisions of MySQL Enterprise Server.
You should also review the notes and advice contained within Section 2.19.1, “Upgrading MySQL”.
