If you're doing this to install a new supervisor and want to run the latest version of Qube! on the new supervisor, match versions between the supervisors first, and then upgrade the new supervisor once the databases have been migrated over to it.
If you're running Qube 6.0 or later, you will need to contact Sales at PipelineFX in order to get your Qube licenses moved over to the new machine. They'll need a MAC address for the new supervisor host.
To migrate a Qube supervisor, you need to migrate both the PostgreSQL databases and the job logs if the job logs are stored on the supervisor's local disk. If your job logs are stored on the network you will not have to move them, simply set the supervisor_logpath on the new supervisor to point to the same network directory as the old supervisor.
It is recommended that you start moving the job logs before you start migrating the PostgreSQL databases, as the job logs will take longer to move.
Don't forget to duplicate any settings you've changed in the old supervisor's qb.conf.
To migrate the PostgreSQL database:
Stop the postgresql-pfx service on the old and new supervisors, then just copy the data directory to the new supervisor host. Make sure that the file ownership and permissions are all preserved (they should belong to the "pfx" user).
The location of the data directory is:
Linux: /usr/local/pfx/pgsql/data
Mac: /Applications/pfx/pgsql/data
Windows: C:\Program Files\pfx\pgsql\data
Once that's done, you should start the postgresql-pfx service and the supervisor service on the new machine.
On the new supervisor, verify that the jobs are present:
qbjobs -u all
Verify that you can see the logs for a random job:
qbout <someJobId>
