Restore CLI backed up config from a 4.1 to a 4.1u1 host

[Ritmo2k]

Is this supported? Looking at backups from identical host's it looks like it could be possible.

Thanks

Should work just fine.

Thanks, I'll image a new usb key with 4.1u1 to revert back if needed.

If you have VMware Workstation you can install ESXi as a virtual machine. You point to the USB stick using the Physical Disk" option. You can then restore the config and test before moving to the physical host.

When you're restoring a backup to an install of a different version you'll want to use the force option (actually you'll have to use it).

Thanks for that tip Dave. You know, the real only PITA i would encounter in reconfiguring from scratch is the vswitch/port config. There any simple way to dump the config in a way to restore it without me manually writing a config using cli commands from scratch?

Thanks!

I think you could get the entire vSwitch config out of esx.conf.  The following is a part of the file (it's in /etc/vmware).

/net/vswitch/child[0000]/name = "vSwitch0"
/net/vswitch/child[0000]/numPorts = "128"
/net/vswitch/child[0000]/portgroup/child[0000]/name = "Management Network"
/net/vswitch/child[0000]/portgroup/child[0000]/teamPolicy/hasUplinkOrder = "true"
/net/vswitch/child[0000]/portgroup/child[0000]/teamPolicy/linkCriteria/beacon = "ignore"

If you look through the file you'll see the entries for VM port groups, security settings, etc.  But given that I can only say I think rather than I know I would stick with creating a vCLI or PowerCLI script to recreate the port groups.
