Overall great results, took about 6 months and much re - and expanded learning (since SONAR 4).  This project involved quite a bit of tracking and I'm sure there are many unneeded fragments.  SDD memory is fast but limited so I would greatly appreciate guidance and experience in how to clean up and only keep / archive the final tracks.
 

Assuming you are using per-project audio folders...
The "Save As" function with the "Copy all audio with project" enabled can create a new project folder with only the audio referenced in the project.

Is this what consolidate audio will collect all project audio does?  It seems to have been removed as a selection from the Utilities , tools(old) menu does.  Is it the same thing?

Had to look up the Consolidate Project Audio function. It is still in the documentation and is at the top of the Utilities menu on my PC.
 
I have never used this feature. From the description it appears to copy all the audio referenced in the project to a subfolder under the project audio folder. Possibly useful for making backups from the Global Audio folder. Not exactly the same as "Save As" which creates a complete project in a new location with the project audio in the new per-project audio folder.
