MailStream Plus on UNIX/Linux- does just running the 8.3.1 'pbprep' (or manually creating the same folder structure) affect MSP 8.3.0 running on the machine?

Operating System: UNIX/Linux
The issue was the user wanted to run the pbprep now, when the admin is available.  
But they don't intend to install 8.3.1 until a few days from now. They wanted to know if pbprep would affect the MSP 830 that is in production on the machine? 

UNIX specialist replied-
It will not affect anything they already have installed.  Also, remember they can create their own /opt/pb area without using the pbprep script.
