Tento script som vytvoril keď som potreboval premigrovať VMs na nové ESX hosty a následne na daných VMs updateovat tools a virtuálny HW. Ak používate vSphere Update Manager, tak tento script Vám pravdepodobne bude slúžiť iba ako inšpirácia. :)

Priebeh scriptu:

• vypne VM
• vyrobí snapshot
• presunie ju na ESX host zadaný v $Destination
• zapne VM
• po naštartovaní VMtools začne ich update
• script VM reštartuje
• po reštarte ju vypne
• upgrade vHW
• zapne VM

Odporúčam tento script spúšťať z PowerCLI konzoly alebo PowerGUI alebo Powershell ISE alebo niečoho podobného. Budete tak môcť sledovať priebeh migrácie.
