I'm looking for some advice on the best upgrade path for the following situation.
We currently have a server running Microsoft Windows 2003 Small Business Server (not R2) with 60 user CALs. I need to replace the server, but at the same time, I need to transition to the standard versions of Windows Server and Exchange. I would like to upgrade to Windows Server 2008 and Exchange Server 2007 at the same time. I understand that we can use the transition pack to convert our current SBS 2003 to Windows Server 2003 standard and Exchange 2003 Standard, but once this is done, how do we go about upgrading to 2008 and Exchange 2007? (Meaning, what licenses would we have to buy?) Would it be better to just skip the transition pack altogether and buy all the new software from scratch?
Any advice on the cheapest way (while maintaining compliance) to accomplish this transition/upgrade would be appreciated.
