what are the roles on the host machine?

migrate will you have both running at the same time?<br />

I think hyper-v is fairly straight forward upgrading the vhd to vhdx

Host is a hyper-v system managing the following VMs:<br />
VM1 is global DC and running on W2K3<br />
VM2 is a SQL server running on W2K8

When you say &quot;migrate&quot; are you talking about setting up a new 2012 R2 host and then setting up 2012 R2 guests and &quot;migrating&quot; the roles and services off the existing onto the new?<br />
<br />
Or, do you mean moving the VMs from one host to the other?<br />
<br />
I suggest the former rather than the latter.

When you say "migrate" are you talking about setting up a new 2012 R2 host and then setting up 2012 R2 guests and "migrating" the roles and services off the existing onto the new?

Or, do you mean moving the VMs from one host to the other?

I suggest the former rather than the latter.

What is the best way to go about this:  Host is on W2K8R2 with 2 VMs (W2K3, W2K8R2). I would like to migrate all of the systems to W2012.  What's the best way to migrate all of these systems to W2012? Are there any good tools to use?

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.

A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
