I’ve been working on an old client proposal for license updates, which still operates on version 10.6.1. In the license table provided by the client, they listed the following items:
- ArcGIS Desktop Concurrent Use Primary Maintenance – Quantity: 1
- ArcGIS Desktop Concurrent Use Secondary Maintenance – Quantity: 3
I wasn’t entirely sure about the differences between these types, so I did a quick online search and came across some historical materials from a couple of years later, including a LinkedIn post and an Esri Canada paper.

It appears that Esri has made significant changes to their licensing structures over the years. These "Primary" and "Secondary" maintenance levels seem to have been tied to Concurrent Use and Single Use licenses, which Esri has been phasing out. The shift is now towards a Named User licensing structure, aligning with ArcGIS Enterprise and ArcGIS Pro.
Given this evolution, it’s possible that these maintenance levels (Primary & Secondary) have been retired? or replaced altogether?.
I couldn't find updated official source from Esri talking more about this, but I’ll continue to dig deeper into this, also any insights or confirmation from others with experience in these older licensing models would be appreciated.
