To upgrade vSphere Replication, you must upgrade certain components of your vSphere environment in the correct order.

Upgrade the components on the protected site before you upgrade the components on the recovery site. If you encounter problems that prevent you from using the protected site when you upgrade the protected site, you can use the recovery site to perform a recovery. The ESXi hosts can be upgraded at any time.
