stable release

[fulltilt]

using :cool:hcs 2.4.7 on 3 servers ...
one system is very bad and slow and its time to setup a new system ..
I know that RC1 is not for use in production system now ... but i only host my own projects on this server ...
My question:
Better waiting for the stable release or go on with my old (damaged) system now?
When did you think is a stable release possible and if i install RC1 is it possible to integrate my old :cool:hcs 2.4.7 webs and upgrade to stable if released?
