I know a decent amount about VMware but just looking for a little bit of advice on the upgrade. Currently the environment has 1 host with 3 Virtuals. ESXi is currently 4.1.1 and they would like to upgrade to 5.5. From what I see I believe they installed ESXi on the raid instead of the typical flash drive. One question I have is, can I just remove VCenter and ESXi, slot a flash drive and install 5.5, attach the datastore and inventory the VMs?
Any recommendations are appreciated.
