I recently bought a new computer, so I would like to transfer my rekordbox library from my old computer over to the new one. Is this possible?

You can transfer your library over to a new computer if you first backup the [Library] in the file menu and then restore the file on the new computer.

Not only can you backup your Collection and Playlists but also set Cues, waveforms, and information on beats and tempos.

You can also backup song files at the same time.
