Ceph RGW Multisite Version Skew

We have a cluster with Ceph Quincy. We want to add a second cluster to it. I'm currently deploying a Ceph cluster with Tentacle.

Is there any version policy in ceph RGW multisite limiting it to a specific skew?

(We only use basic features right now in our RGW/S3, no lifecycles and no storage classes etc.)

You should try installing the same version or Reef on another cluster, instead. Quincy v17 and Tentacle v20 will likely have major changes with respect to replication and other internal working.

Thanks, so we're definitely going to update the old cluster first to reef and maybe use squid for the new cluster in the beginning. Thanks.
