Problem solving might be more efficient if you would tell me what your other DAW is.
Generally speaking, from DAWs that support AAF format such as ProTools, Cubase, Nuendo, etc., you only need to export the audio, track name and automation part in AAF format, and save the instrument, tempo and label part in MIDI file, you can convert Most of the core content.
These are hard to convert:
1. Musical instruments. Instruments cannot be transferred between DAWs due to differences in how different DAWs call instrument plug-ins.
2. Effect plug-ins and specific configuration. The reason is the same as above. You can use the plugin's own presets to save, but this is also time-intensive for a larger project.
3. Features unique to DAWs. Such as Studio One's arrangement track, Chord track, the way these tracks are used are DAW-specific.
