Upgrading
From OpenPLi Wiki
OpenPLi distinguishes between minor releases and major releases. Major release for example are when you upgrade lest say from version 6.X to version 7.X and minor releases are when you upgrade from 7.1 to 7.2
Major releases (so like 6 => 7) you must flash, preferably using the menu and choosing the backup option, then everything is restored after the flash. When there is no Hard disk present use an USB stick.
Minor releases (like 6.0 => 6.2) are updates, so updating will suffice!
