To upgrade and retain programming you'll need the upgrade kit. Just plunking in the new software will wipe the slate clean. Also, your line numbering will change when you move the trunk cards around. The PRI will be lines 1 to 23 or 31 to 53 on 6.1 software. Are you sure you need both the 6 port and 2 port fiber expansions? If not you won't need XC software.

Sounds like maybe you should bring a telephone company in.

Good luck!
