Is the DiscoveryProfile JobID unique across multiple copies of NPM ?

I am working on making sure that we have NPM discoveries configured in multiple NPM systems. The Discoveries are based on CMDB records of subnets that we use internally.

Now that I'm working with 3 instances of NPM, I see a possible problem.  I had previously used the ProfileID column to identify the discovery and then compare the  Name column against the CMDB discovery name.

Now I'm sure the ProfileID will NOT be unique across the different NPM instances.

Question:

Can I use the JobID column as a unique identifier across multiple NPM instances?

If the answer is no, then I can construct my own unique identifier based on the NPM instance and the ProfileID.
