Hello Karl- The upgrade should be pretty straight forward for those versions. You had typed ‘1.15.12’ and ‘1.16.3’— I suspect you meant ‘5.15.12’ and ’5.16.3’.
If you can have all the applications ‘drain’ all messages, that is the best. You then get fresh kahadb files created by 5.16.3. Otherwise: 1. Take note of queues and # of messages in each 2. Stop the old 5.15.12 2. Copy the kahadb files from 5.15.12 to the new 5.16.3 3. Start up the new 5.16.3 4. Verify queues and message counts Hope this helps!
