Currently I am on Ubuntu 18.04, CQRlog 2.5.2(001) and MariaDB 10.5.11 and I am planning to upgrade to Ubuntu 20.04.
My cqrlog database on laptop replicate to database on raspberrypi in both directions.
CQRlog on latop is configured to use ip address and port 3306 instead of 'Save log data on local machine'.
As I am not any kind of coder it cost me some effort and time to get it worked. AFAIK default sql for Ubuntu 20.04 is MySQL, not MariaDB.
So, the question is: Is any safe way to save my current MariaDB configuration including replication to raspberrypi and later restore it after upgrade to 20.04? Or is nothing to worry about?
