Traffic Router 3.0 works with all of the 2.x components regardless of which OS they are on, but TR must be on Centos 7. If you already have a 2.x version of TR on Centos 7 then 'yum update traffic_router' will clean up the old version leaving only the logs and the .properties files. It will also install the new dependencies. The new version is started with 'systemctl start traffic_router' instead of 'service tomcat start'. That should be it unless you've done some manual customizations of TR 2.x, like for instance, if you wrote your own systemd unit file.

On Centos7, will we be able to use 3.0 with 2.x releases as is currently done today. If already on Centos7, What is the upgrade story from 2.2 to 3.0? —Eric > On Jun 5, 2018, at 12:03 PM, Jeff Elsloo <[email protected]> wrote: > > In light of the major changes introduced into Traffic Router with PR > 2331, I would like to call a vote to increase the major version of the > project to 3.0.0.
