Folks, 

I came across a case of an old job where I could see that A Lab Report that had one PID had only Samples on a completely different SID/PID.  I believe it was connected primarily through the Lab_Report_ID and the ID field (Although it may have also been connected with Lab_Report_Number as well)

I'm cleaning up these old sites and Projects. It looks like the Chemistry Samples are on the correct spot but that the Lab Report has been assigned the wrong PID. 

Looking for ideas on ways to fix this safely and remove the lab report from the wrong PID.
