How would you copy the BGP prefix 192.168.42.0/24 from VRF-A.inet.0 to VRF-B.inet.0?
A.
Use a VRF import policy on the destination VRF to match the desired prefix.
B.
Use an import policy on the BGP neighbor configured with family inet-vpn to add a target
community that VRF-B imports.
C.
Use a VRF export policy in VRF-A to copy the route from the source VRF to the destination
VRF.
D.
Use a RIB group policy to copy the route from the bgp.l3vpn.0 table to the VRF-B.inet.0 table.

With B your policy could match the prefix and the VPN-A community. You could then use community add to add the VPN-B community that the VPN-B vrf-import policy is matching against.
