I want to rebuild my SBS 2008 box but do not have a backup of system state on the SBS2003 server.
I am ok with cleaing out AD etc but am unsure about removing Exchange 2007 from the Exchange 2003 bit before I do the DCPROMO, has anyone got any guidence on this?

How far down the migration did it go? Did it actually install Exchange?

I would probably just crash the SBS2008 box and then manually remove the Exchange 2007 Administrative group using ADSIEdit.

Then run a METADATA Cleanup as per: http://www.petri.co.il/delete_failed_dcs_from_ad.htm

TO be honest it is only the IIS that is completly screwed by a 3rd party app someone installed but I am too nervous to mess with it and get a leave term problem lying. So I though just starting over might be the best option and then came across all this crap with exchange

Ahh well in that case just repair it :)

There is an SBS repair guide here that covers most things: http://technet.microsoft.com/en-us/library/sbs-2008-repair-guide(WS.10).aspx

You will need to do that in the Exchange Console (there will be 2 routing group connectors, see Step 11 of my guide here: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2881-Migrate-Small-Business-Server-2003-to-Exchange-2010-and-Windows-2008-R2.html)

I would seriously be looking to repair it though instead of crashnig out the migration if all the problem is IIS.

I have been doing some reading on Exchange since your last comment, as you seem very experienced and I appreciate your help, I just would like to confirm the follwong before I proceed. Just to let you know the IIS different bits fail as the thrid party app gets installed and it stemmed from an incorrect installation of a 32 bit webserver etc. I cannot really see an appropriate fix on the links you gave me.

I turn off the new server.
Enable DHCP on the OLD and make sure clients have the old DNS server entries
Run metadata cleanup and seize all the FSMO roles back to old server
I transfer the connectors and then use adsiedit to remove exchange
I reboot the source server and check all is functioning.
Reformat the new server give it a different name and IP in the migration txt file?
and start over.

Will the above action remove Exchange 2007 from the 2003 exchange management console or will I still need to delete.

PS I read somewhere that you cannot install Exchange again once this has happened, am I likely to bump into this problem also, if so I think I may abandon the whole migration and just setup the new server on as a new AD domain and transfer all machines to a new domain etc.

Where did you read that? There is no reason why you wouldn't be able to re-install Exchange.

I've done this a couple of times in the past and not had problems, it's possible not all entries have been removed which is preventing the Exchange install or the SBS2003 server is not in good health.

What does the Exchange 2003 Best Practice Analyzer say?

did you run the sourceprep tool on the SBS2003 server? This prepares the domain and prepares for the Exchange 2007 installation.

I ran this first time and got an exchange error. I thjen rebooted and ran it again created a new answer file, this time I did not get the error but I did not do the reboot. Would this be related? Obviously al this had been done a week ago.

yes it would be related, because you cleaned up the admin group and needed to re-create it, this tool will do that.

You will need to start the SBS2008 installation from scratch.

What another migration or a new domain etc? I am happy to run through the above again with the correct reboots etc or is it going to fail at the same point?

If you come across this scenario, I have to be honest either fix the problem or forget about the migration. I ended up with some problems with exchange and started to run out of time.

Thank you for all your help and time.
