Importing Old Configuration to CIS6

Have my config file all ready for when CIS6 goes final.
Has anyone had any issues so far with this, with importation and usability ?

As far as I am aware, the configs between CIS 5.x & CIS 6 are not compatible (at least in part). I would not recommend this.

Thanks for info Kail, was just curious if anyone had succesfully done this.
