Hello. Please, can you advise about this:
Im have a few datacenters under control of VCenter Server 5.5 + Update Manager 5.1. All hosts, connected to VCenter are ESX 5.0\5.1 Standart. Each ESX hypervisor installed on internal-storage. I have a configuration backup of each ESX host (take it with esxi-5-0-host-backup-restore-gui-utility-powercli-based).
And i want to: 1) Upgrade ESXs to 5.1u1 and 2) migrate every ESX from HDD to USB stick.
Can i achive this only with Update Manager? After a few hours of learning looks like i cant use it this way?
So my only way is to make clean install ESX 5.1u1 to usb stick, configure ip, then restore configuration to host?
