V1 using V2 page in Include"

If I develop a page in V1.  Can I use a V1 page include to reference a V2 page?  Can I use a V2 page include to reference a V1 page?

V1 and V2 are not compatible and can’t be mixed.

John is correct. Skuid does not support the use of mixing page versions.

Can v1 and v2 be in the same environment ? V1 using V1 and V2 works with V2.?

Yes, you can have V1 and V2 running in the same org (or Platform instance). You can link between the pages/navigate/etc.
