Integration Server - migration of code

I am trying to migrate my Services and other flows created in one box to another box. Both of them have IS4.6, wM Enterprise 5.01 and the Broker Package installed. I have recreated all the necessary components, like broker aliases, DB aliases, etc.
My current usage is to trigger transactions from the Commerce Server website via XML. But after I migrated the code to the new box and repointed the COM components initiating the XML to point to the new box, I am not able to trigger the transactions. (Looks like the IS does not even receive the request). What am I missing?? Would appreciate any help here.
