Hello everyone. I was sporting OFW on my PS3 slim until I thought it was time to explore the possibilities of CFW (3.55 kmeaw). However, that came at the sacrifice of using PSN. I recently purchased another PS3 (CECHA01) for a steal and decided that I wanted to use THAT one for my hombrew/hacking needs and subsequently upgrade my slim to OFW to access PSN. The thing is that the fat PS3 is still running 2.42 OFW, and while I'm not entirely sure of what I can do with OtherOS, I've been advised to refrain from upgrading it past the point of no return.
What I wanted to ask everyone is what exactly can I do with the OtherOS feature? Is it really worth staying at a lower firmware? Additionally, how would I be able to transfer all of the data stored on my slim's HDD (including savedata and backups) to my fat's HDD (which I've replaced with a 500 GB drive) without having to rip everything all over again? Does CFW outperform the capabilities of OtherOS? Is it possible to have both at the same time? Thank you all very much for your input.
