migrating H2 database to postgres

[Karl Sommer]

Hello. I get the dialog to change the confluence database from H2 to another because we are using it in a productive environment now. Searching the internet an trying some hours I gave up and keep the H2 database now. Are there documents how this can be done? 

Best regards
