it should help plan any
setup and implemetation of SD. You could pull in resources from the v6 box to the CMDB on the NS7 box. However Rob is 100% right on. You're going to needs at least one NS7 box for the Service Desk Solution.
So conceivably, you could have an NS6 box, with data being imported via connector to the NS7 box, and then passing the required data onto the Service Desk Box.
Or you could upgrade to CMS7 (which has it's own areas to be cautious with).
