I have some older deployed OVF/OVA appliances from 3rd parties such as Trend Deep Security (and Vshield), CISCO virtual appliances and other misc deployed appliances that came from vendors as OVF/OVA style deployments..
They deployed with older versions of vm hardware. In some cases as old as VM Version 4 which is extremely old.
Most are 7 or 8.
Being that these are 3rd party should i be changing / upgrading the virtual hardware in the vms? Is this ok to do or should they be left as is?
I am wanting to get them upgraded for obvious reasons and especially as of late due to the latest Intell / Spectre / Meltdown situation.
