currently I am using Thingsboard community edition 3.4 with the use of postgresql database. I try to migrate the things board data including the devices, rule chain, and dashboard to the new host as the requirement. Both of the servers currently used use the installation in the Window, can I get advice/suggestions on how to migrate the current things board data to the new host?
You could make a backup of the entire PostgreSQL database of ThingsBoard and move it to the new server.
example with pg_dump:
sudo -Hiu postgres pg_dump thingsboard > thingsboard.sql.bak
