V6 vs. V8 Virtual Disks and upgrading

I see that V8 uses .swdsk files for VDs and V6 uses .ibv files.
Is there a performance difference between the two?
What will happen to the .ibv files during the upgrade?
V8 allows cache larger than 512MB, can the cache size be changed on the old VDs after the upgrade?

V6 and V8 have incompatible data formats. You need to migrate to a newer ones.
IBV functionality (CDP, snapshots, thin-provisioning etc) is deprecated. Use LSFS instead of it as it does incorporate everything.
You need to re-create or put LUs down and patch XML header telling L1 cache size to StarWind core.

Can V8 and V6 run on the same machine using different ports?

I don't think so...
