https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=39314 Bug ID: 39314 Summary: RabbitMQ can't upgrade from 3.x to 4.x without running a data migration on 3.13 Change sponsored?: --- Product: Koha Version: Main Hardware: All OS: All Status: NEW Severity: major Priority: P5 - low Component: Installation and upgrade (command-line installer) Assignee: koha-bugs@lists.koha-community.org Reporter: victor@tuxayo.net QA Contact: testopia@bugs.koha-community.org CC: tomascohen@gmail.com Reported to Debian as it affects their next release which will do a jump from 3.10 to 4.0: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1100165#10 Which can't work: https://www.rabbitmq.com/docs/upgrade «You can only upgrade to RabbitMQ 4.0 from RabbitMQ 3.13.» «stable feature flags have to be enabled before the upgrade. The upgrade will fail if you miss this step.» See there more more details. ----- For us: is there still data in RabbitMQ when stopping a Koha instance and upgrading it? I recall reading that the DB was basically mirroring the message queue data during a discussion about the actual need for a dedicated message queue. Does it mean the koha-common package can wipe the RabbitMQ data which will allow it to start without issue? -- You are receiving this mail because: You are the assignee for the bug.
