Hi,
Thanks for your answers, welcoming.
1. OK
2. OK for licensing
3. OK, In my procedure I'll put off the vms befor upgrade *
4. OK
5. I I found this KB : http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1022140
I think upgrade using vmware update Manager.
I don't necessarily need the latest version, so i think stay to ESXI 4.1.
* I wish perform an entire Backup of the VMS.
How long will take copy to external media ? What is the best copy method?
Thanks a lot for the help.
