after you have transitoined to full server, you aquire the exchange enterprise license + enterprise CALs and move your data to the new server.

then uninstall the standard server from the old exchangeserver..

the old exchangeserver being the SBS :-)

Incidentally, there are 2 versions of Exchange Standard and Enterprise, there are also features which are specific to standard or enterprise CAL's (different from the server licensing)

But do I have to migrate to another server (hardware) or can I just upgrade the SBS server

No you cannot just upgrade the SBS server you will need a new server, please have a read of my guide.

Waauu. Nice guide you have written.

Thanks.

to transition from sbs03 to exchange enterprise 2007 / 2010, you first transition to the full 2003 before migrating to 2010.. there is no direct way - unless you migrate to sbs 2008 first -but thats a waste of time..

There is a direct way and it has been done.  I have documented it in my guide which incidentally I actually did the migration when I wrote.

what did you do with the CALs form the sbs->full transition?

You need to buy seperate CAL's, as I said in my initial post, the best thing regarding licensing is to speak with Microsoft.

But CAL's do not stop the migration.

it would then be cheaper to use the transition pack. or else the cals are lost..
I just asked our licensing specialist, and the transition pack is a lot cheaper, she says..

like I said in my initial post, I was not aware of a transition pack for Windows SBS2003 to Windows 2008 (I may be wrong as I said)

So I need Transition Pack from SBS2003 to 2008 end then upgrade to Enterprise Exchange license?
Do you have any microsoft product numbers for these licenses?

I don't believe you can transition from SBS2003 to Windows 2008 the transition pack was for SBS2003 to Windows 2003 and Exchange 2003.

Your best bet is to talk to a Microsoft Licensing Specialist.
