Sorry in advance if this gets confusing...

So I've beaten World Of Final Fantasy for the PS4. This was NOT the maxima version - it was the original version that came out before.

I have now downloaded the Balthier summon as a free dlc.

Now, I am thinking of upgrading to the maxima version. Just to remind, this is the PS4 version.

My questions:

1 - If I upgrade to maxima, will I lose my Balthier summon dlc?

2 - Same as above but for Sephiroth summon dlc.

3 - If I upgrade to maxima, will it keep my save file, or will I have to start over?
