World Of Final Fantasy PS4 Version Question

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?

As far as i know, it shouldn't make you lose any dlc you've obtained. Not sure about being able to use older saves though.

You keep your save file, and it has no effect on DLC you already have.

Thanks for the replies, and yep I can confirm this as I went ahead and upgraded.

I didn't lose Balthier, and I was able to continue with my save file. So all is well there.

I don't know how to obtain the Sephiroth summon though. I never had him in the first place, and I can't see him in the ps store...
