So the docker install [discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md) install the LATEST… how to select a stable version?

Downgrading isn’t supported, you can’t roll back to beta or stable until they pass the current tests-passed. You can use the commit ID as per [this topic](https://meta.discourse.org/t/change-tracking-branch-for-your-discourse-instance/17014), but it’s very unlikely a routine upgrade is the cause - Discourse _isn’t_ prone to spontaneous combustion.
Do you have sufficient free space on the server? Have you disabled all plugins and re-tried?

OP is trying to restore a backup with a schema from 2017 so this is not what he is trying to do.
Might this be related to the fact that delayed column drops are working differently nowadays?

Fair enough, I was going by the title, which said he was upgrading to beta9 +184.

Yes I was using v1.9 earlier and now I was planning to upgrade to v2.2.
I switched from Bitnami to a dedicated Docker install. Somehow latest+latest was installed. So I got v2.3.0.beta9+184 where the backup import failed.
So have to look up how to install a specific docker version

Might be similar to this [Trouble upgrading from 1.9.0.beta11](https://meta.discourse.org/t/trouble-upgrading-from-1-9-0-beta11/105219)

Yes! The solution basically is:
