Question regarding VMware vCenter Server Appliance (VMware-VCSA-all-6.5.0-7070488.iso)

[MKB1961]

I currently have VMware vCenter Server Appliance v5.50.30700 Build 7460865 and I'd like to download and install the trial for VMware vCenter Server Appliance (VMware-VCSA-all-6.5.0-7070488.iso) to show my manager the usefulness of it, and to also be able to provide critical & security patches for both version 5.5 esxi & version 6.0 esxi VMware hosts (and their vm guests as well) using Update Manager, which is not available via my Center Server Appliance v5.50.30700 Build 7460865.

If I run the vCenter Appliance v6.5 trial, and need to roll back to v5.5 would it be possible?

Need bit more information. So you are planning on deploying VCSA6.5 and migrate your ESXi hosts to it? Do you use DVS or VSS? If using VSS, you can easily disconnect from 5.5 environment and add to to 6.5. If you have to roll back, just disconnect from 6.5 and add it back to 5.5. Its a bit different is using DVS. But if you add a 6.5 host in VCSA 6.5 then you won't be able to add it to 5.5 vCenter.
