A couple of, hopefully easy, questions regarding the upgrade using DISM.

I have a windows server 2008 R2 Standard machine I would like to upgrade to Enterprise to use more than 32 Gigs of memory. I have been searching for the answer to my first question for a few days with no luck.

Question 1: How long does this usually take, on average, given a modern computer...2 processors, at least 32 Gigs of memory.

Question 2: This machine has Hyper-V role and has 1 VM running on it, 2 others are setup, but not running. I know I need to stop the VM from running before i start at least. Is there any other issues with updating a Hyper-V rolled server?

    I would recommed you document yoru hyper-v guest and hyper-v configuration settings before hand. I expect you just plan to ruthe windows install and in-place.

    I would expect the upgrade to take 2 hours. 1 actual hour plus a reboot and some wiggle room. I would expect that a new install would be faster than an update and the install can just run clean where an install has to read the registry, etc.

    If this Hyper-v is running the company - I would try to recommend purchasing a 2nd server before the upgrade. Having two hyper-v means you can elimante single point of failing if one server has issues.

    Thank you for the answer, The Hyper-V is just a test right now really, so it is not "major" but I know the person running the test would not like to loose it.

    And I do plant o do a DISM to upgrade to enterprise, Really do not want to do a clean install as there is quite a bit of configuration on the server itself for some financial software.
