    If you Clone to New Virtual Machine, does that remove the original server's SID on the newly cloned box?

    Or do you need to run sysprep on the original box first, then clone?

    Welcome to the Community - You can have vCenetr sysprep your new VM or you can do it manually - it is one of the options as you go through the clone wizard -

    Do you know where that is listed as an option?  I don't recall seeing it.

    Welcome to this community.

    refer the below kb for sysprep detial

    For windows 2008 and later you dont need to run sysprep as its placed inside the os itself.

    No it does not remove SID from the cloned machine.

    Every time you clone the machine you are require to do it with customize option to provide new SID for the new virtual machine

    Method is as follow

    This is a hoary old chestnut but every time i see a discussion on SIDs I paste this link to give a reality check to those who may be misled.

    Mr Russinovich is someone who actually knows something about SIDs

    I have been cloning VMs for some years now without touching the SIDs - no sysprep, no NewSID, no problems :smileyhappy: with the notable exception of AD servers but hey...who in their right mind would be cloning one of them anyway?

    Yes I did somany clonings without touching SID but, when Exchange server/ AD comes into the picture you will be bump.

    For more info about SID :
