Official comment
I confirmed this functionality for another customer just the other day:
- import songs to rekordbox; allow them to analyse for all items available
- export the XML file from rekordbox (File > Export Collection in XML format)
- open MiK and import the same songs into MiK, allow them to analyse
- click the Personalize tab
- click Export Cue Points for Existing Files
- close MiK, go back to rekordbox
- click the refresh button beside the rekordbox xml tree item
- right-click on the MIK Cue Points playlist, select Import Playlist; if prompted to overwrite, click yes
