When I open an old WL12 montage in Safe Mode (File/Open/Audio Montage/Open (SafeMode)) I do not get the WL13 conversion pop-up and the opened file has no v13-suffix.
Is this intentional and does it mean that the file is not “converted”?
No, the montage is converted to WaveLab 13 and the version on disk is modified and cannot be reused in WaveLab 12, when you use the “Open Safe” special function. But thhis will change in WaveLab 13.0.10
