The vCloud NFV platform architecture components have interdependencies. When upgrading components, you must follow a particular upgrade sequence for the minimal impact to the running workloads and to ensure that there are no interoperability issues during the platform upgrade process.
-
This upgrade sequence applies to both 2-Pod and 3-Pod design.
-
When you upgrade vCenter Server to 6.5 version, the connectivity of the vCenter Server with VMware vSphere® Replication™ and VMware Site Recovery Manager™ will not work. To enable the connectivity, upgrade VMware vSphere® Replication™ and VMware Site Recovery Manager™ to the compatible versions.
-
After upgrading VMware vCenter Server, verify whether the host preparation is required for NSX Data Center for vSphere by scanning the baseline using VMware Update Manager. The scan result must not show any warning/error for conflicting VIBs for vxlan and vdpi.
