You upgrade the vSphere Replication appliance and any additional vSphere Replication servers by using a downloaded ISO image and the VRMS Appliance Management Interface.

Note: If you uncomment any of the configurations in /etc/vmware/hbrsrv.xml, regardless if you change the configuration value, the value remains the same after you upgrade vSphere Replication.

vSphere Replication Upgrade Scenarios

You use the ISO file and the VRMS Appliance Management Interface to upgrade from vSphere Replication 8.6.x or 8.7.x to vSphere Replication 8.8.

For the full list of supported upgrade paths, see the Compatibility Matrices for vSphere Replication 8.8.x at https://docs.vmware.com/en/vSphere-Replication/8.8/rn/compatibility-matrices-for-vsphere-replication-88/index.html.
