I could be snarky and respond "All currently supported versions of GTM (10.x - 11.x) and DNS (12.x -13.x) support datacenter failover", but I'm intrigued by your use of the word 'seamless'. In my experience, a failover event always has a seam (however small it may be). In order to achieve true seamlessness, you must use a proactive migration strategy, rather than a reactive failover strategy.

 

Could you expound a little bit on how you expect to achieve seamlessness or which configuration objects you have versioning concerns about?
