Can I export Rock Band, Rock Band 2, Lego: Rock Band, Green Day: Rock Band, or The Beatles: Rock Band into Rock Band 4?

The Beatles: Rock Band is a standalone title and will not export into any other Rock Band game, including Rock Band 4. You will not be able to export these other legacy titles directly into Rock Band 4 - they must have been previously exported in order to re-download in Rock band 4.
