Play cfw previously installed pkg games on ofw

Hello guys, I have a slim ps3 with 4.85 rebug CFW. My question is: is it possible to install pkg backup games on it and than install 4.86 OFW? My goal is to play online on 4,86 OFW my backup games previously installed on 4.85 CFW, in order to avoid a possible cid ban. If this is not possible , whats the best way to go online with a 4.86 rebug cfw?Thanks in advance
