Hello Anthony,
I want to write a upgrade guide for Hydra (just like we have for Kratos) but havent been able to get around to it.
Andrew already said it, check the UPGRADE.md, migrate database and be wary of any breaking changes that might affect you (in general there are very few).
Please let me know how it goes and if you run into any errors, as it is quite hard to reproduce a "real" upgrade from e.g. v1.0 to v1.9.

01/26/2022, 4:13 PMok, i just went /w v1.0.8 since it mentions schema change at v1.0.9 and it connects to existing postgres w/o error
but i notice it doesn't response to health check..
