I thought the migration from 2007 to 2010 was complete, but received errors when trying to uninstall the 2007 mailbox role regarding the public folders.
I realised then that the public folder data hadn't replicated to the 2010 server even though replication was setup a number of days ago. The amount of data to replicate is very small, it's just a shared calendar.
Only event of note in the logs is "Cannot find route to Mailbox Server CN=Exch2007"
At present, the 2007 server only has the mailbox role on it - presumably it will need the hub transport role on there for the public folders to replicate?
But even if this is the case, the hub transport role was on there before for a week or so after the public folder replication was setup and no data was transferred.
So I guess 2 questions:
1. Do I need to put the hub transport role back on the 2007 server in order to resolve the public folder issue?
2. What further steps should I take to troubleshoot the replication?
BTW - I have looked in adsiedit for the CN=Servers container as mentioned in a number of similar posts - however, this container isn't empty.
I have also run the update-publicfolderhierarchy cmdlet.
2007 is running on SBS 2008
2010 is running on Win2012
