how VUM process work.

Dear team,

please let me know below process is correct if we use VUM to upgrade host / cluster.

1)IMPORT THE ISO TO UPDATE MANAGER

2)CREATE A UPARDE BASELINE

3)ATTACH UPGRADE BASELINE TO CLUSTER / HOST

4) REMEDIATE (MIGRATE VMS TO OTHER HOST,PUT HOST INTO A MAITAINANCE MODE, UPGRADE HOST, REBOOT, EXIT MAITAINCE MODE = UPGRADE OTHER  ESX HOST IN  A CLUSTER)

regards

Mr Vmware
