Finish SBS 2011 Migration to different hardware

Hello,

I am trying to migrate SBS 2011 to different hardware. I installed SBS in migration mode on the new hardware and everything is working fine. The one thing I didn't do was migrate exchange. When I was migrating exchange installation gave me an error likely since the new hardware had 4GB ram and as I understand 8GB is required. This is okay as we don't use exchange at this time and the hardware we are moving to is only temporary until we can get another server in.

In the migration wizard the final steps talks about demoting the source server, it says to read the instructions for how to do this that it links to:

http://technet.microsoft.com/en-us/library/cc626220.aspx

This takes you to a page that allows you to download a word document. In that document under "finish migration" it tells you to first move the arbitration database to a new mailbox and then uninstall the database. I couldn't move it since I didn't have another server to move it to so I simply deleted this arbitration mailbox which went fine.

When I go to uninstall exchange from the control panel management console is grayed out if I leave the server roles to uninstall checked, so I uncheck those (other wise I get an error that one of the controls is grayed out).

This lets me continue with the uninstallation, however, it gives these errors before it starts:

I have tried removing these public folders from exchange power shell but I get an error that they don't exist. I also don't know how to resolve the problems with the bridgehead and transport errors. Any help would be greatly appreciated.

Thank you in advance.
