Pro Tools 10 was the last version that could open a session with SD2 files and automatically convert them to WAV (BWF) files once this is done, you should be able to open the converted session happily in Pro Tools 12. Note that the older your Pro Tools sessions, the more likely it is that the audio file format used will be Sound Designer II, as that was the default audio file format for Pro Tools in the early years. The same applies to session files from versions of Pro Tools earlier than v5.1. If the audio files are Sound Designer II (SD2) format, you will need to find a system with Pro Tools 10 or earlier installed. Pro Tools 12 can only open sessions where the audio files are in WAV or AIFF formats. The main one is to do with the audio file format. So, although Pro Tools 12 will open sessions from v5.1 upwards, there are some caveats to bear in mind.
