Purging old records

I know there is the “Database Purge and Summarize” process, but the purgeable objects are just:
Job Details, Indirect Labor, Journal Details, and Change Log.

If I run the process, would it then allow deletion of items that referenced them?

In particular, I’ve got tons of Part records in V8 that haven’t been used since 2003. If I did the Purge with a date of 12/31/2004, would I then be able to delete those Part records?

We have about 4500 parts in the system, but only about 300 are actually in use. Our data goes back to when we were on Vista 4 in 1997.
