[Kea-users] upgrade kea with db backend

[Wagner Vlastimil - HZS Ústeckého kraje]

Hi

I have dozens servers with Kea, now i will change hardware with new version of linux (centos 7.9 ---> almalinux 9).
And there is new version of Kea and of course DB schema version.
How is best practice to upgrade, its not possible upgrade all servers in one time.
Is somewhere db schema version compatibility matrix?
