We've forced installs to migrate to modern hunk storage, but the old tables and data are still hanging around as a safety net. We should remove them after a few months of clear sailing.

Just wanted to keep track of this as I suspect it may have been forgotten. D9290 adds "modern" hunk storage for Differential, but I don't think we ever pushed forward with this... On our install, I migrated all Differential hunks to the modern storage over 6 months ago and haven't seen any major issues.
