Putting PSP save data on PS Vita?

Having a really hard time with this. Using Content manager. I tried putting my PSP save data (Dissidia 012) in the PS VITA folder and in documents(That’s where it is searching, the documents folder) and no content is found. Dissidia 012 as a game is working just fine, but I can’t get my save data. How do I do this

It doesn’t want to work because Dissidia is ass.
