How to upgrade from MySQL 5.5 to MySQL 9.7 (LTS)

Back up first (mysqldump --all-databases), and read the release notes before moving to a new branch.

Ubuntu / Debian

sudo apt update
sudo apt install --only-upgrade mysql-server

RHEL / Rocky / AlmaLinux

sudo dnf upgrade mysql-server

Docker

docker pull mysql:9.7

Since 8.0.16 the server upgrades its system tables itself on first start; there's no separate mysql_upgrade step.
