Back up first

Always back up first. Stack Watch briefs are automated heuristics over public release notes and vulnerability databases. They can be wrong or incomplete. You are responsible for validating upgrades in your own environment. We never invent CVE IDs or issue counts — if a number is missing, it was not found.
