Before An Upgrade
- Before performing an upgrade, read the release notes of the new release.
- Learn the new features of the new release.
- Understand the incompatibilities that may exist between releases.
- Before performing an upgrade, back up the databases.
- Including the
mysql database that contains the grant tables.
- Rename the old
mysqld before installing a newer one.
- For example, rename the current server from
mysqld to mysqld-VERSION.
- If the new
mysqld does something unexpected, shut it down and restart the old mysqld.
