Essentials/Essentials Plus both the kits will allow you to do cold migration.
Power off VM, migrate, you have all three options available to you
a) Change host - required shared datastore between source and target host
b) change datastore - required both source and target datastore to be visible to host, since vm will remain registered with the same host, just files will move
c) change both - VM files and host registration both can also be moved using this one
hope this helps.
