Can I do a 2003 SBS Exchange to 2012 server and 2013 Exchange if I DONT migrate exchange, but just import the PST files?

I know you cannot do a direct migration and I know there are code two type tools that sorta allow it with cross forest and other domains etc, but it all seems like a lot of work for 10 users.  so here is my question.  Can I build up a new 2012 server with AD , DNS, DHCP etc.  and then install fresh on the 2012 box 2013 exchange and create new mailboxes for the AD users already there (from the 2003 AD migration) and just import the PST files that I got from doing an EXMERGE on the 2003 SBS server?  Would I have to completely decommission the 2003 box before exchange 2013 is installed leaving mail in limbo for a day while all that happened?

if you're able to get 2010 SP3 in there as an interim step then you can migrate; else no since 2003 needs to be completely gone before putting in an 2013 exchange installation

Migrate SBS 2003 to Windows Standard 2012 with Exchange 2013

If you have the kit to build new servers I would build a completely new Forest and run them in parallel. That will allow you to replicate everything (permissions, groups, email addresses, users etc) without any pressure.
Then when ready, switch the email around, migrate the desktops and import the email.

If something went wrong, switch it back and have the users login via OWA.

I am not sure what you mean by "kit" and I understand that if I built up an entirely new network and domain I could move them over one at a time the rest using OWA, but is that really what you mean?  I would rather not have to hit every desktop and copy profiles etc.  that never seems to work very well in the end.

Kit - hardware, servers, resources whatever you want to call it. Late night posting by me results in some odd words used occasionally.

Going to a new Forest never works well - that is why it is something I only do if I really have no other option.
You could put a trust in place, then grant permissions that way. I would look at doing a big bang migration through - coexistence between two separate environments does not always provide the expected results.

My reference to OWA was that you went big bang, moved the desktops etc, but if something went wrong, end users can get their email by OWA while the problems are resolved.

I've requested that this question be deleted for the following reason:

no one actually answered or addressed the question.  there are lots of ways to migrate to exchange, but that was not really what I was looking for.  No one addressed moving just PSTs within the same forest.
Seth SimmonsSr. Systems AdministratorCommented:
ok, let's go over this again then.
You want to export mailboxes to pst files from the SBS 2003 server then import in the exchange 2013 server.
Yes, that can be done, though as you said mail would be in limbo since the SBS server needs to be removed entirely first.
This also introduces another step - the SBS server would be your domain controller so unless you have another one there, you need to put one in first and move DHCP (if you use it) over to the new box, have clients point to that server for DNS and remove SBS.

Once that is gone, then you can install exchange 2013, create new mailboxes and import the pst files.
