Hello , We don't want to upgrade Pega 7.1.7 as it is a sunset app but we need to upgrade Server OS etc.. From Redhat Linux 6.x to 7.x . Per platform support guide Pega 7.1.7 is supported only with RHEL 6.x . But, checking if any of you have Pega 7.1.7 on RHEL 7.x.
***Edited by Moderator Marissa to update platform capability tags****
We do have internal test systems running 7.1.x on Redhat 7, but if you do have to upgrade your OS (not officially supported configuration), please perform extensive testing, do not recommend run mission critical applications, though.
