As I just wrote on the wiki , upgrade through the lifecycle of Debian stable is generally not a problem. What's painful is from one Debian release to another (ie: upgrading a rabbitmq-server cluster for example, is noticeably painful). Though you don't really *have* to upgrade, you could migrate your workload to a new Debian release deployment. Of course, you'd need more servers to do that, but at the same time, after 3 years of production, you probably aren't against a refresh of your infrastructure.
