Unfortunately the migration path is rather convoluted. Exchange 2003 and 2013 have no direct coexistence support. You'll need to introduce an intermediate exchange server such as 2007 or 2010, move the mailboxes, then introduce 2013 and move them again.

Alternative you can export mailboxes to PST and then import them. But that has the downside that significant metadata is lost and the DR scenario if something goes wrong is more complicated.

And finally there are 3rd party services than can automate a direct migration from 2003 to 2013. But the cost is not cheap. If it were me, I recommend the first path. Keeping control of your data, making regular backups, and having a way back is worth its weight in gold.

As far as migrating the other stuff, TechNet has plenty of guidance for migrating ADDS, file servers, DHCP, etc. All that is straightforward and SBS doesn't introduce any particular challenges. Exchange (and SharePoint if you'd use it) will be the big hurdles. And because of that, there are no easy-to-follow "thus just works" migration docs. Migrating from that many old products to new ones takes skill and knowledge that sadly can't be condensed into a simple guide.

Hi there,

beside exchange, there is a mid step that needs to be done, regarding migrating sbs2003 domain to windows 2012.
You have to install windows 2012 essentials (get trial from somewhere) in transition mode first. That is going to allow you to migrate AD domain services to windows 2012. When you install Essentials, you will get wizard to add new domain controller to a existing domain, next, next..wait till it is done, and you have new AD DC wich run 2012.

 After that you can simple, via power shell or cmd, upgrade essentials to standard edition. One command with serial key of windows standard.

To prepare SBS for migration: http://technet.microsoft.com/en-us/library/jj200136.aspx

After that is done, you install dhcp, and reconfigure dhcp to give new dns server to clients.
Migrate FSMO roles, printers, etc...

Now you can install new exchange 2010 or 2007 (trial) and migrate exchange 2003. This is mid step, as Cliff said.

Link i used when I did this migration myself: http://technet.microsoft.com/en-us/library/jj200112.aspx
There are few other steps, but this will get you started.

"then install exchange import psts"

To install Exchange 2013 you would have to completely eliminate all traces of Exchange 2003.
That means you lose everything inside Exchange - the PST files are just the data.

- permissions
- email addresses
- links between calendars
- nickname contents (they will not work for internal recipients without additional work).

The double hop migration as already outlined is the best way to do this, as you will not lose all of the information. While you can document the settings, you will miss things. You are looking at documenting 10 years of changes, even with a small number of users that will be difficult to do 100%.

Don't try and shortcut the migration. Do it as outlined and it will not cause much business disruption. PST migration method is very disruptive.

Simon.

If you are installing 2012 standard as your original question suggests then there is no migration mode and you'll only start a 21 day countdown on SBS when you transfer the FSMO roles... so that could be the very last thing you do before retiring the SBS server. A fairly common practice truthfully.

Essentials is not required to migrate Active Directory. Only install Essentials if you plan on keeping it or want the essentials features.

Well, I just followed MS guide, on that link, that used essentials. It was easy to install and required only 1 command to upgrade it to standard.

That is how I have done it, with no problem. Did not try with some other versions of win.
