Migrate Public Folders from Exchange 2007 to Exchange 2010, uninstall Exchange 2010

I cannot seem to uninstall (decommission) my legacy Exchange 2007 server due to the public folder replication.  I have read all the other posts regarding migrating these folders, and was sucessfull in replicating to the Exchagne 2010 server.  Now that all the public folders exist on Exchange 2010, I want to Decomission 2007.  Can't uninstall because the Public Folders still exist on 2007.  I open the EMC and manual undo replication between servers, but I still can't uninstall.  Also a few hours later, all the replication settings are back in place.  I've manually removed replication between servers at least 3 times and it keeps coming back.

I get the default uninstall error in the Exchange Readiness Check (during uninstallation) pointing me to http://go.microsoft.com/fwlink/?linkid=81409.  I have followed these articles and still having problems.  Any help is appreciated!  I don't even use the public folders, but needless to say I do not want to break my new Exchange 2010 server for the future.  Just trying to decommission 2007 properly.
