Hi,
I have a 4.1 licence with the option to upgrade (free) to 5.x. One vCenter server as a VM managing 4 hosts with iSCSI SAN.
Which route would you take to upgrade vCenter:
1) In place upgrade (after backing up the VM)
2) Create brand new VM, install vCenter 5.x and remove the hosts from 4.1 and add to 5.x?
------
Notes and thoughts:
My vCenter sever is self contained - MSSQL and all supporting services except DNS and mail run on it.
Option 1 is probably the easiest.
Option 2 gives a warm and fuzzy feeling of starting anew without cruft. However, it scares me that it might break the system and I suspect I'll lose my performance stats going back 3 years.
What do you folk think? Not done this particular upgrade before...
Many thanks - Tim
