(adsbygoogle = window.adsbygoogle || []).push({}); As the title says, is it safe to install Waninkoko's CFW ontop of Geohots?

By ontop I mean, for example..
I had OFW, then I Jailbreak'ed using Geohot, now I want to install Waninkoko.
So is it a-ok to just update to Waninkoko while im on Geohot?
Or do I have to go OFW then update to Waninkoko?

I'm running PS3 Slim (120GB) CECH 2002-A
