Tks for answer Troy,
I know this procedure, but in my case I have 13 ESXs and around 300 templates dispatched on around 20 different datastores ...
In my testcase, now, I don't know which templates depends of each ESX.
So I try to found a tips to have all templates directly listed on my new virtual server if it's possible, if not I will need to connect again my ESX to VC3.5,
noticed the correlation betweek ESX-Templates-datastore...
New idea ? :-)
