I thought we could go right from 22.8 to 23.8 (so I only added 23.8 in #18) BUT it turns out ClickHouse had other plans for us:

Per release notes for Altinity 23.8:

Upgrading from 20.3 and older to 22.9 and newer should be done through an intermediate version if there are any ReplicatedMergeTree tables; otherwise, the server with the new version will not start. #40641. Here is a possible upgrade path if you are upgrading from 20.3: 20.3 -> 22.8 -> 23.3 -> 23.8

If you upgrade from versions prior to 22.9, you should either upgrade all replicas at once or disable compress_marks and compress_primary_key merge tree settings before upgrade, or upgrade through an intermediate version, where the compressed marks are supported but not enabled by default, such as 23.3.

Downgrading from 23.8 to version 23.5 or below may fail due to changes in sparse columns serialization, see #55153 for possible workaround.
