Hi mscik,
However, you do have to take care of Transport Rules and Journaling Rules. Normally, these are exported from Exchange 2007 and imported into Exchange 2010 when you install the Hub Transport Server role, but there
are circumstances where you have to do this manually. To migrate Transport Rules from Exchange 2007, logon to the Exchange 2007 Hub Transport Server, open an Exchange Management Shell and enter the following command:
Export-TransportRuleCollection -FileName C:\Export_Transport_Rules.xml
Copy the resulting file to the Exchange 2010 Hub Transport Server, open an Exchange Management Shell and enter the following command:
[Byte[]]$Data = Get-Content -Path " C:\Export_Transport_Rules.xml " -Encoding Byte -ReadCount 0
Import-TransportRuleCollection -FileData $Data
When you open the Exchange 2010 Management Console, the Transport Rules will now be not only visible but also fully functional on the Exchange 2010 Hub Transport Servers.
