Does the old game passes from V1 still work?

Recently, I heard that game passes from V1 would stop transferring over to V2 if you haven’t transferred them already.

I know that you have to join the old game, but the pass, then join the new game, but I am unsure whether this will work now.

Can someone please enlighten me about whether this still works?

Gamepasses from V1 dont transfer to V2

Ah, thanks.
