Hi all! About the two database migrations marked as Breaking Change [1] [2], I have two questions: 1. do you have any approx benchmark on how it could take on MySQL on X amount of data? 2. are the migrations backward compatible with Hydra version <

v1.9.0

? I want to be sure not to break old kube pods during the rolling update and/or trying to run the migration manually before the hydra update.

Do you have a staging environment? Even if you get the positive answer here it can still break.

Thanks for the answer @limited-tent-11422. That's the point. Manually testing on a dev/staging environment it's not so reliable imho. I would like to know if the migrations have been designed to be compatible with older application versions or not.
