Migrating DC from physical machine to a VM

I need to move Active Directory from an existing physical machine (roles: ADDS, DHCP, DNS, IIS, Network Policy and Access Services and Print and Document Services) and put it on a VM (Hyper-V) as a guest: 2012 R2 Standard, 8 GB RAM, Intel Xeon CPU E5-2430 v2 @2.50 GHz (6 cores, 12 logical processors).
I plan on building a fresh VM install of 2012 R2, activate the AD-DS role as well as other FSMO roles and promote it as a DC.

***My question is, how do I migrate all the Active Directory data in this scenario?  I see a lot of stuff out there on this but nothing that matches the scenario given above. Would I be safe in just setting AD up with the same domain name, server settings, DNS, DHCP scope settings the same etc. and then demote the old DC and go live with the new VM DC?

*Note: this is a standalone DC, single DC

Thanks in advance for your advice!

Thank you!
