Update UCS 5.0.9 to 5.2.0

My issue fits this topic, so I’ll post here rather than starting a new one.

I’m trying to upgrade from 5.0-9 to 5.2 our secondary DC is showing this as a problem with upgrade.

We have moved to Keycloack and I was under the impression anything to do with the simplesamlphp is now resolved.

My question is, how to resolve this issue without spending time renewing the certs? All I want is UCS 5.2 with keycloak.

Edit:
I had a look at Renewing the SSL certificates but it’s way too involving to follow. Unless there’s now other solution.
