We are currently running IBM MQ 9.1.0.5 on RHEL 7.9. Since this version of RHEL has announced EOS we are planning to migrate to RHEL 8.
is IBM MQ 9.1.0.5 compatible with RHEL 8.10 ?
Yes, IBM MQ 9.1 is supported on RHEL 8.10 - see this page (defaults to showing 9.1, select the most recent maintenance level to view the latest set of supported platforms): https://www.ibm.com/software/reports/compatibility/clarity-reports/report/html/softwareReqsForProduct?deliverableId=B560B760819A11E6B5854315721876AE&osPlatforms=Linux#!
