Server Upgrade - suggestions for pathway

[SteveB_NI]

I'm hoping someone with more server knowledge than me will kindly point me in the right direction here - to assist with my server upgrade plans for Summer 2018 (not too long now!)

 

Current Set Up:

 

Server 01 - Windows Server 2008R2 - Roles: Active Directory, DHCP, DNS, File Services - contains 1TB of usage storage (its in a RAID set up) Pupil data 300GB, Staff data 300GB

 

Server 02 - Windows Server 2008R2 - Roles: Active Directory, DHCP, DNS, File Services, WDS, WSUS

 

 

New Server (not even switched on yet!)

 

Disk Storage: 2 x 400GB SSDs & 4 x 1TB HDDs. Our license will allow us to install up to the latest version of Server 2016 I believe.

 

My initial proposal would be to split the new server into at least 2 x Virtual servers, and replace both existing servers above with this, but is this the right way of doing it, and how?!

 

Thanks for your time & any feedback received - much appreciated!
