How to migrate all netbox data to another netbox server properly?

[ngocnd1]

Hi everyone
Is there anyone had migrate all data to another server
Secarino:
I have a couple of server as develop environment running netbox and netbox sync (both of them running as docker)
And I also had a couple of server as prd enviroment running netbox and netbox-sync (both of them running on vms not docker)
For now i want to migrate all database from dev to prd.
What i had done?
pg_dump to get backup file from dev and cp it to prd and restore.
=> Both environment already had same database as well. But problem is when i implement netbox-sync to update any new but result is duplicated number of virtual machines and ip.
=> Is there anyone has experience with it or how to figureout?
Thanks
