I'm not very sure how is it packaged, exactly, this is left to reviewer to confirm.

I would add some pre section for this section explaining why we ever need to rollback to previous storage version. Maybe add some example of issue was reported. Another idea would be to leave this document as it is but add another docs for known issues, where we put the issue BP were experiencing and link to this doc which should be a solution for known issues

We haven't actually relased a breaking version until now, I think. It'd be better we test the instructions in this doc work right after the release, so to update doc accordingly.
Summary
mina-storage-converter, avoiding a full rebootstrap from the remote S3 ledger bucketDetails
Node operators upgrading past 3.3.0 may later need to roll back. Without this guide, the only option is a time-consuming full rebootstrap. The
mina-storage-convertertool can convert the local RocksDB state between versions, but the process is undocumented — this page fills that gap.Key design choices in the guide:
*wildcard for the RocksDB version path so operators don't need to know which RocksDB version is bundled with each Mina releaseNODE_DIR,SOURCE_VERSION,TARGET_VERSION) consistently across Debian and Docker sectionsdocker run ... -c "..."one-liner that installs toolbox packages and runs the converter in one shotmina-configis not persisted outside the container
