Hi There,
We are running on vSpehre 5.5 with 30 ESXi hosts and one Windows vCenter server, and planning to upgrade the infrastructure to vSphere 6.5 U1.
We would like to follow green field approach for upgrading the platform. That means instead upgrading the existing vCenter server, deploy the new vCenter server appliance (without native HA), install, configure then migrate the ESXi hosts to new vCenter server, finally decommission the Windows vCenter server.
Though googled,I could not get right information for this approach I need to follow. When I install new VCSA 6.5, do I need to deploy that linked mode to be able to migrate the ESXi hosts and VMs? What is the best practice for this approach? Could you help me with high level steps ?
Thanks in advance
