Will we be able to see/play our old levels with LBPOnline?

Really looking forward to the 4th! Sadly my LBP1/2 account was basically on my dads old old olllld work account from 2007🥴 so my old account although I remember my name I can't obviously use that for LBPOnline, but I published quite a lot of levels and films, so with LBPOnline will I be able to search my old account and play those old levels or is it only a selected number of levels which have been added?

Thanks in advance!
