First and foremost, this list isn't meant for support, please refer to

lists for support purposes.

You can't skip releases when upgrading, you have to fully upgrade to
Debian 9 (including updates) before upgrading to Debian 10.

Always best to check your setup in a VM or a machine with snapshots
first, but at a glance MySQL has been replaced with MariaDB (at least
they're highly compatible but if you use any sort of configuration
manager or metapackages or scripts that refer to these for your
deployment, you'll have to update those).
