Old server upgrade / migration - SBS 2003 - Windows Server 2012

Hi im looking to upgrade some of our servers and was after some advice/suggestions.

I currently have 3 old server running different tasks from Domain controller (SBS 2003) as well as a DNS/web server.

Im thinking about getting one possibly two server's and moving everything onto this.

I would put Windows Server 2012 on with Exchange 2013.

All the users on this are remote and some use different domains.

Would I be ok doing this first off and I take it I can have a SSL certificate on the exchange server for different domains?

Also what is the best way to migrate the SBS data over so things like login details (passwords) and current mailboxes?

Any advice would be great thanks

You cannot do what you plan to do.
There is no path from SBS 2003 (Exchange 2003) straight to Exchange 2013.
Therefore you have two options.

1. Migrate to Exchange 2010, remove SBS 2003, then migrate again.
2. Build a completely new Forest, and do a manual migration.

Option 1 will allow you to move everything with pretty much no downtime.
Option 2 is highly disruptive, even with a lot of planning as you have to recreate everything in the existing domain.

SSL certificate - if you have a UC (aka SAN) type certificate then you can support as many domains as you like.

Ok thanks Simon that's pretty much what I thought.

So when you say migrate to Exchange 2010 then remove SBS 2003, then migrate again do you mean migrate to SBS 2011then move from that over to 2012?

If so would you recommend getting an old server and migrate over to SBS 2011 and then go from that over to the new server running 2012 and Exchange 2013?

Thanks

Ok so possibly install 2008R2/Exchange 2010 onto an old server then migrate that over to the new box running 2012/Exchange 2013

Having only ever done SBS migrations is it fairly straight forward to migrate from SBS 2003 over to 200r2/Exchange 2010?

Would I just join the server to the domain (as a member server)? Will that allow me to migrate the mailboxes as well as active directory data?

Sorry for all the question!

Thanks

ok this could be a question for another thread but was thinking about maybe moving over to Windows Azure?

Not knowing anything about this really would I be right in saying you pay a monthly fee to have a hosted server? I can still install Windows server 2012 onto it with Exchange etc and will all work in the same way I just don't have a physical server?

Thanks
