How to Upgrade

SwiftMQ 9.2.2 defines two AMQP listeners on port 5672 (plain) and 5671 (SSL/TLS) to be able to run AMQP out of the box. They will also be added as part of the rolling upgrade process as specified on the links below. If you don't need these listeners, you may either delete them *after* the upgrade or use the "NOAMQP" option on the new release *during* the upgrade on the first start of the router start script of the new release, e.g:

        ./smqr1 NOAMQP

or

        ./smqr1_replicated NOAMQP

The option work on HA and non-HA releases but only on the very first start where the config files will be upgraded.
