Hello,

I am trying to upgrade from 0.27.0 (very old, I know!) to 1.12.

In the [instructions](https://docs.temporal.io/docs/server/versions-and-dependencies#upgrade-your-version-of-temporal) it says to reach out on the forums for upgrade instructions from versions older than 1.0.0, so here I am. Any help would be much appreciated!

We test only sequential updates starting from 1.0.0. There were bunch of breaking changes including persistence level in 0.28.0 and 1.0.0. It means that data stored with 0.27.0 can’t be read with 1.0.0 and next versions. I would suggest you to setup new cluster and switch users to it.

Yeah good suggestion, that is what we ended up deciding to do. Fortunately this will only be a one time cost as future upgrades can be done incrementally.
