Active HP-UX admin here.

the software being run is SAP R3/Oracle and there is plans to replace it, but that is not happening anytime soon due to the usual delays associated with ERP migrations.

License cost is a red herring here especially when dealing with enterprise applications from the likes of like SAP, Oracle and IBM, heck were probably paying as much for our SAP on SUSE subscriptions as we do for our HPUX licenses, and the real license costs is with the applications and databases.

And it's not that long ago(say 2014) that there were niches where the only real cost effective way to get enough single box io performance was to bye an non x68 box that came with it's own unix, so there is a lot of systems out there where the hardware aren't actually old enough for an 1:1 migration to make commercial sense and rewrites/redesigns of ERP software is risky with most projects overrun both the time and budgets by an order of magnitude, if they don't outright fail to deliver an new system.
