BGP ROS7

Hi ! Can any help me with BGP to migrate on ROS 7 ?
ROS 6 BGP working config

/routing bgp peer

add in-filter=UBNT name=UBNT out-filter=OUT_MAIN remote-address=193.x.x.x remote-as=asnumber ttl=default
add in-filter=MT name=MT out-filter=OUT_MAIN remote-address=213.x.x.x remote-as=asnumber
add in-filter=MT2 name=MT2 out-filter=OUT_MAIN remote-address=213.x.x.x remote-as=asnumber
/routing filter
add chain=UBNT set-bgp-weight=33300
