Upgrading & moving exchange 2007 to 2013

So should I only upgrade to 2010 for now, and in a few months or whenever it's supported, upgrade to it then?

How do you know for sure that exchange 2013 is not supported on win 2012 R2?

From here: Exchange 2013 SP1 will support 2012 R2

I won't presume to tell you that you should upgrade to 2010. Or use 2012 instead of 2012 R2. Or whether you should upgrade at all and just wait. Your resources, time, budget, are your own. So only you can make those decisions.

As far as support, Microsoft always publishes system requirements. Exchange 2013 is here:

http://technet.microsoft.com/en-us/library/aa996719(v=exchg.150).aspx

You can see that 2012 R2 is *not* listed as a supported OS. When they add support, they'll update this document. You should always be checking system requirements before installing software. While the OS is a great example, if you are just making assumptions you  could also run into other things where you don't meet minimum requirements. You'd be surprised how many "IT Pros" I saw buy 2008 R2 licenses a few years ago for their existing servers at the time, just to find out they didn't have a processor that supported 64-bits, or didn't support the necessary instruction sets, etc. A lot of money spent on a license and CALs...just to either have to bust their budget to buy new servers. Or sit on the unused licenses. System requirements aren't suggestions and shouldn't be glossed over.

But if you need explicit further proof, there is always the Exchange team itself, which maintains a blog and wrote this about 2012 R2:

And while it isn't normal to "update" an old blog entry, I'm fairly sure they will post a new one when support is actually added. And that hasn't come out yet.

EEhotline:

On that website, it lists a checklist, but it only shows the instructions for the first step.
How do I perform the rest of the steps on the checklist?

Checklist

I used this to do the upgrade in my lab:

I think I will just upgrade to Exchange 2010 for now, and maybe later this year, we'll upgrade to 2013.

Thanks guys, will just upgrade to exchange 2010 for now.
