Service Desk 7.0 requires a 64-bit system to be installed on.  Also it requires a CMDB 7 server for licensing.  So what you would need is 1 CMDB 7 system and 1 64-bit Windows 2003 server in order for SD7 to isntall.

Long and short, no

So, I can upgrade my current NS 6 to 7 and use it as CMDB 7 system, and I need another 64-bit system for DS.

Well, what about licensing? Can I use my current Helpdesk license to upgrade to SD7, or will I need to get additional licenses?

As far as I know there is no "on the box upgrade" for upgrading Help Desk to SD 7.
First of all you need a NS 7 server with the SD7 solution installed ( this is for licensing). Then you need a sperate 64-bit server for the Aactual Service Desk 7 server.
You can migrate categories, incidents and KB articles, but you would have to keep your Help Desk server up and running to access your old incidents.

Thank you so much.

Well, for the SQL server, does it have to be a separate server, or I can install it on the same server as SD7?

Thank you so much Rob for your help.

Onle last question regarding SD7.

I'm going to upgrade my current Helpdesk 6 licnese to Service Desk 7 license. Do I need any additional licenses to use Change Management and Problem Management facilities that are available in Service Desk 7?
