This patch also reverts previous changes which were merged for migration to the newer disk format. We will be bringing these changes in subsequent releases. But we wish to add protection in this release such that future release migrations are protected. Revert "fs: Migration should handle bucketConfigs as regular objects. (#4482)" This reverts commit976870a391. Revert "fs: Migrate object metadata to objects directory. (#4195)" This reverts commit76f4f20609.
