Dear VMWARE-Friend,
I tried Upgrading our ESXi 4.x to ESXi 5.x
Backup Before Upgrade
PATH=%PATH%;"C:\Program Files (x86)\VMware vSphere CLI\bin"
vicfg-cfgbackup.pl --server server-ip -s backup-of-esxi-host
After the Upgrade
Observations:
Have to redo all the vNetwokring for this host:
this includes all vSwitches, all Port Groups.
Restore from vicfg-cfgbackup didn't work ( Backup for ver 4)
1) Reconnect the Server
2) Reconfigure Networking From the Console Interface
Static IP
DNS
3) Add Licensing
4) Enable Services NTP, SSH
Host-<configuration->Security Profile->properties->Select Service->options->Select Start
Add the NTP Server
esxcli storage core claimrule convert
No /adv/Disk/MaskLUNs config entry to convert
Upgrade the VMs
