Hmmmm, interesting. That (recreating over 100 datastores) is the biggest reason I asked. The amount of downtime we have in production is extremely minimal and a lot of customers opt out of any maintenance periods thus making it more difficult. Obviously, if there are major consequences for increasing the datastores I would do it the longer way and just suck it up, but if there are really no downsides with the newer vSphere versions it makes the idea of just increasing them look better and better.
We are using 3Par storage, and will most definitely ask them for their insight.
Thanks!
