Hi,
It might be easier if you could describe the desired output/behavior.
I assume by reverse path, you mean inbound traffic.
What I gathered from the Cisco config is you are applying local-preference of 500 to specific prefixes towards TCL [To-TCL] and AES [To-AES out]. However, since this eBGP I doubt local-preference would be the method to influence your inbound traffic, unless I missed something..
I believe the export policies could have been simplified by rewritting them.
You can use "show route table inet.0 advertising-protocol bgp x.x.x.x" to view the routes being announced to the neighbors. If you have a similar capture before the migration, you could compare against as well.
Cheers,
Ashvin
