Upgrading Vendor ESXi Over Stock
Posted on 2014-04-02
I have an HP server with stock ESX 5.1 on it, along with a 2TB VM (standalone/non-clustered).
I want to upgrade this server to ESX 5.5 U1 using HPs vendor ESXi image.
- Can I just upgrade the HP 5.5 image on top of the 5.1 stock? or should I wipe ESX and start clean?
- Are there any risks in leaving the VM on the server? It is stored on another set of local disks (VFMS 5). I'd prefer not to have to move 2 TB to another server and back and have 2 sets of longer downtime, but it'd be worth it if there's potential for issues with the upgrade process...
