Seems silly to migrate your existing OSPFv2 to an extra instance of 
OSPFv3, leaving 2 separate OSPFv3 instances.  Why not just stick with 
your existing OSPFv2 and add OSPFv3 for IPv6?  Or if you want to 
migrate your IPv4 IGP, go directly to IS-IS so you can have a single 
link-state database, single process, etc. for both IPv4 and IPv6.
