Explanation
Check the MySQL Reference Manual before performing any upgrade: Always consult the section on upgrading to see whether there are any notes pertaining to the type of upgrade you're performing. If so, follow the recommended procedures described there. Check the change note sections for versions more recent than your current version to make sure that you're aware of what has changed since your original install. Note particularly any changes that are not backward compatible with your current version because they may require modifications to your existing applications if you upgrade.
