Transitioning from SBS 2003 R2 standard to full Windows server and Exchange using Transition pack

Hi,
I have a problem with SBS licensing and max users ceiling of 75 and I need to resolve this issue as soon as possible with as little down time as possible. So far from what I have gathered my best option is to use transition pack to move away from SBS. Currently I am running DCHP, PDM, and IAS and of course Exchange on a DELL 2850 box (Dual core I think) Xeon 2.80 GHz with 4 gig ram.  Am I correct in assuming all I need to do is to purchase the transition pack and enough licenses and install them on my SBS server in which case  I will be running Server 2003 and Exchange 2003 in the same box and if so do you think my current hardware is muscular enough to handle 100 users? How pain free is it REALLY to do the transition and how much down time should I expect?
Thank s

Expect half a work day for the transition if you've never done it before. Once you transition (very straight forward automated process), you will need to account for the time it will take to reapply the Server service packs. Make sure that they are downloaded ahead of time for quick install. Obviously make sure any CALs you need to accomodate the new Exchange users or Terminal Service users are purchased and ready to install after the transition. This only really becomes a difficult project when you need to migrate server applications to different servers, which you don't.

There's a very good Transition Pack How-to here:  http://sbsurl.com/tphowto

The transition itself is relatively easy... shouldn't take more than an hour or so.  But you should consider moving your Exchange Server to another box since it would then be running on your domain controller, which isn't recommended if it's not SBS.

To clarify the CALs comment made by Addihul above... you can only purchase up to 75 transition CALs.  Anything above that would require standard core CALs.
