Issue/Introduction
Limitations:
During the upgrade process from VCF 4.3.x/4.4.x/4.5.x to VCF 5.x, the vCenter versions will be in mixed mode.
Following functionalities will be limited or not supported:
Single Pane of Glass (SPOG) – Single Pane of Glass to view all the vCenter versions will be available on the highest version vCenter in the environment during the upgrade process.
Add/Delete WLD of 4.3.x/4.4.x/4.5.x and 5.x will not be supported during the upgrade process.
Recommendation to backup VCs after every VC upgrade or VC patch application.
Do not run parallel upgrades if Enhanced linked mode is enabled.
Symptoms:
vCenter UI Showing warning message/banner : "Your environment is now in mixed mode. It is recommended you update your linked vCenter Servers to the same version"
This mode is essential for VCF customers since upgrading from VCF 4.3.x/4.4.x/4.5.x to 5.x can take time.
