We have a PowerEdge T300 Server that is around 6 years old. Currently it is running the free version of ESXi 4.1 off of a 4 GB flash drive that is connected directly to the motherboard. The virtual machines are stored on a RAID array (directly attached storage).
Is it possible to upgrade from 4.1 to 6.0 or will I need to do a fresh install of 6.0 on my flash drive? If I install 6.0 will it automatically recognize my storage repository on the DAS (RAID 5 array).
Also, would 6.0 even work on this old of a server or should I be looking at something like 5.0?
Thanks
