Has anyone tried upgrading Redhat from 7 to Redhat 8 in-place with Viya 3.5 installed? The easiest is to do in-place but will the Viya software/SAS run afterwards?
I suggest you ask Tech Support for an official answer. In my experience OS upgrades in place are not recommended and there would be no guarantee SAS would still work.
" SAS Viya can only be upgraded on Red Hat Enterprise Linux 8.x following a new deployment on that operating system. You cannot upgrade the operating system to the newer version of Linux without a full redeployment of SAS Viya."
Better contact SAS Tech Support they will let you know if there are changes to this or if there are work arounds.
The SAS Users Group for Administrators (SUGA) is open to all SAS administrators and architects who install, update, manage or maintain a SAS deployment.
