F5 GTM Sync Groups Requirements

Hello all, 

Throughout my environments I've only seen GTM Sync Groups deployed between like hardware and firmware deployments.  Is it possible to successfully deploy a virtual GTM running the same firmware as a hardware GTM ?

I have a single i2600 and would like to implement redundancy but due to cost, I would like to consider adding a virtual appliance if possible.  Would there be an issues in doing that?

Yes, you can deploy GTM in a different platform (ex. hardware and virtual) as long as you have the same GTM and big3d version. But you want to properly the size of VE so that you will not face any performance issues.
