Project plan to upgrade from CMS 6 to CMS 7

I'm looking for feedback from anyone who may have a project plan to share for a CMS 7 install.  I've got a rough version, but looking for feedback from others.  We currently only use Helpdesk 6 and DS 6.8 SP1.  After every task is done, Software and Inventory solution are installed.  We've got the servers built, Altiris Agent installed on every client system, we've got software policies, we've got software installs to go with the policies, systems are remediating, software portal is set up for users, we're doing patch management, we've got the SAN space, we've set up the network properly for software to be distributed, pcAnywhere in use.  Assume all endpoints have the AClient already.

So, short version, a spreadsheet with time assigned to each task or each solution, broken down by resource, with a time estimate for each.  Does not include Deployment Solution 6.9 SP3 or ServiceDesk 7, I'll post about that in the respective forums.
