Hi all, is there any known way to migrate certificates from one netmaker installation (with default sqllite db) to another with PostgreSQL database?

Are you asking about the letsencrypt browser certs or the mq certs. The browser certs are tied to a domain and can't be moved unless the new server has the same https endpoints as the original. The MQ certs are stored in database so they can be moved with the database.

sorry i wrote certificates meaning the ext clients configuration files (and qr codes). I'm in the process of reinstalling a new netmaker machine and I would like to maintain the configuration files used so far

the extclient conf is maintained in the database and the conf file and qr code is generated on the fly. So if you have migrated the database, you will have all the data

ok thanks! i don't know sqllite but will have a look on how to export data

everything in the database is stored as key/value pairs
