Michael Dürig commented on OAK-6941:
------------------------------------

Not a strict backwards compatibility issue, but for Oak 1.6 versions prior to {{oak-run}} 1.6.8 have an issue that can lead to sever data corruption in some cases. See OAK-7050.

> h4. Problem statement
> For compacting the segmentstore using {{oak-run}}, the safest option is to use the same version of {{oak-run}} as the Oak version used to generate the repository. Yet, sometimes, a newer {{oak-run}} version is recommended to benefit of bug fixes and improvements, but not every combination of source repo and oak-run is safe to use and the user needs a way to check the compatibility. Thus, the users need a tool that guides the decision of which version to use.
> h4. Requirements
> * Easy to decide what {{oak-run}} version should be used for a certain Oak version
> * Up to date with the latest releases
> * Machine readable for scripting
> * Include details on the benefits of using a certain version (release notes)
> * Blacklist of versions that should not be used (with alternatives)
> h4. Solution
> TBD
