Exchange 2010 redundancy

I have an exchange 2010 server with all roles.  I have a backup exchange box off-site and wanted to get it setup so if the main one dies I can have the backup resume.  Used to use 3rd party applications to do this but I hear its easy to do with exchange 2010?  What all is required to setup and if a disaster occurs, how do you get the other one active (dns change internally and change mail delivery from firewall to hit backup server?).

What is the underlying OS? If it is Enterprise edition of Windows then you can setup a DAG, which will replicate the data, then use a CAS Array and a load balancer.
If the underlying OS on either end is standard edition then you are going to migrate to a new machine with Enterprise edition or Windows 2012 standard.

2008 r2 standard.  So I can't replicate exchange with std edition08 on exchange 2010 without 3rd party tools, but server 2012 with exchange 2010 allows it?
Correct - because it uses clustering.
The clustering technologies are not in Windows 2008 R2 standard, but they are in Windows 2012 standard (because there is no Enterprise edition).

I would look at the costs between third party tools and replacing the Windows OS.

Once I get 2012 OS for the exchange servers what is the process?  Should we go to exchange 2013 at the same time, what's gained?
