Which packets must be removed after migrating to v4

[Volkan_Bulbul]

Which packets are unnecessary on debian and be removed after migrating to v4 ?

[brocaar]

After a successful migration:

• chirpstack-gateway-bridge is updated to the latest version v4.x
• chirpstack is a newly installed package (v4.x)
• chirpstack-application-server can be removed
• chirpstack-network-server can be removed

Probably chirpstack will not start when chirpstack-application-server is installed, as their default ports (8080) would collide.
