Hi,
When VMware ask you "This is a moved or copied VM" this action have no impact in your SID (SID concern your Guest OS). When you choice "moved" no change will be applicated to your vmx, but if you select "copied" for example a new mac address will generate. But it is only a change apply to your VM.
if you deploy a VM using a template, you can generate a new SID using the customization wizard.
Otherwise, you can download newsid.exe into your VM and execute it.
Regards,
Julien
