Yes, that's understandable, but question was about "transit period" when at
some point we had part of RGW's upgraded and some of them were still in
Jewel. At that time we had a lot of complains from S3 users, who couldn't
access their buckets randomly. We did several upgrades in last years and it
was first time when old RGW's were not able to work with buckets "touched"
with new version RGW's.
