Migrating from single server instance of ADFS on Windows 2012 R2 to a Windows 2012 R2 ADFS farm

Hello.  We recently started using Office 365 Skype for Business.  We setup a single server instance of ADFS on Windows 2012 R2 so we could single sign-on to Office 365.  This is just a single Windows 2012 R2 box with the ADFS role installed.  We aren't using the ADFS Proxy.  We also use ADFS for Federation with some other outside entities.  We are now looking to utilize Office 365 even more and we need a geographically dispersed ADFS solution.  We should have setup a more robust ADFS infrastructure from the beginning but we didn't.  I've seen plenty of guides for migrating from older versions of ADFS to ADFS on Windows 2012 R2 but I haven't seen anything showing if you can migrate from single server to a farm.  Is that possible or would we need to just start from scratch?  Ideally we'd like to setup something in parallel and migrate by just making a DNS change.  Also, can a Windows 2012 R2 ADFS farm using the Windows Internal Database be geographically dispersed?

You dont need to "migrate" it, just run the AD FS wizard on the second box and join it to the farm. If for some reason you want to move the existing server to a new box, you can follow the 2012 guide and export the configuration, the cmdlets are pretty much the same.

And yes, you can use WID.

Thanks for the reply.  I want to confirm.  The existing ADFS server is a single server install not a single server in a farm install.  Can I do what you're describing in that case?  If not and I do need to move the existing configuration to a new server that was installed as a farm install can I still do the export of the configuration even though the configuration will be changing from a single server install to an install that's part of a farm?

It looks like the default installation is a farm install so I guess you're advice is right that I just need to install the second server and add it to the farm.  Thanks for the answer!
