EDIT 3 - EVERYONE BOOT UP GROUND ZEROES AND SELECT UPLOAD SAVE WHEN YOU'RE READY BEFORE YOU START PLAYING TPP. IT DOESN'T READ IT LOCALLY
So since a bunch of people have played MGS5: TPP now, do we have confirmation yet exactly what we need to do in Ground Zeroes for each item to be transferred over to The Phantom Pain.

I'll try to summarize as best I can since there are a ton of repeat questions here (note: I don't have TPP yet but have been following this thread)
- Use the guide in the OP to see all the POWs, targets, and soldiers you need to extract
- You do not need to extract everyone in one playthrough, though you do need to successfully complete the mission each time for the extractions to register. For example, if you rescue the 2 POWs in "Eliminate Renegade Threat", kill the targets and finish the mission, then begin the mission again and extract the two targets, that should give you all 4 in TPP
- You need to collect all the XOF patches to unlock the Deja Vu and Jamais Vu bonus missions. If you beat Deja Vu on Normal, you get the classic Snake skin in TPP. Some users here have reported that you just need to finish the mission and not recreate all the scenes and ace the quiz, though that is unconfirmed. It is also unconfirmed if the Grey Fox skin you get from beating Deja Vu on hard transfers over
- It is also unconfirmed if the Raiden skins you get by beating Jamais Vu on Normal and Hard Transfer over
- As far as we can tell, S Ranks, collecting all tapes, getting all trophies, 100% saves, and beating all missions on hard do not have any effect
- You upload your save data from the title screen after finishing the prologue in TPP. You can upload and download your data at any time, and multiple times if you go back to GZ and do more, and it should update
- Personnel and unlocks in TPP do not all appear immediately. Some appear only after beating certain missions or fulfilling other requirements. From what I've read, you need to finish at least until Mission 12 to have everything transfer and/or be available for R&D
- Yes, the servers are down on Xbox. No, there isn't an ETA to fix them

Current information so far:
- Need to extract 19 POWs and Agents through out the missions for 19 Volunteers in TPP. Just needs to be done on Normal.
- Need to beat Ground Zeroes Mission for the Sneaksuit Costume
- Need to beat Deja Vu for Snake Costume
- Need to beat Deja Vu Hard for Grey Fox Costume
- Need to beat Jamuis Vu for Raiden Costume
- Need to beat Jamuis Vu Hard for Raiden White Costume
No news on whether cassette tapes, S ranks, or percent completion matter at all.
