Provide a way how to yum update without risking having update packages without migration script run
- Lock the application's packages at a specific version (using the yum
version-lock plugin for example)
- Provide a script that completes the various (formerly manual) upgrade steps, so that we can ensure they are done in the correct order. And also give the user
the option to backup the DB and other sundry items to make sure the
process happens in the correct order.
Because users don't always read the docs prior to issuing 'yum update', and we should do whatever possible to not leave them with a broken system.
