LBP GOTY edition - will my original save work?

[AaronSOLDIER]

So basically I want to get the GOTY edition but will sell my original to put towards it, but will my original save work? I don't want to have to re 100% all the levels.

Also, I have 1 of the MGS packs which are on the disc, so should I delete my DLC and redownload it all except for that one pack?

Finally, it since the latest update is on the disc (or an older update like 1.20 for example), so I'm guessing I delete the update data inside the 'Game Data' folder?

Thanks.
