Can you show me a couple things? 1) The output of ps auxw | grep memcached 2) Which version of memcached you're using 3) Which version of python_memcached you're using Christian -- Christian Hammond - chip...@chipx86.com Review Board - http://www.reviewboard.org Beanbag, Inc. - http://www.beanbaginc.com On Fri, Apr 18, 2014 at 2:31 AM, Paul Fee <paul.f....@gmail.com> wrote: > Hi all, > > I'm testing a migration from 1.5 to 1.7.22. > > Summary of migration steps. > > Old system: > ========= > Ubuntu 10.04 > Manual installation of Reviewboard 1.5 > Dump database: $ mysqldump -u admin -p reviewboard > > /tmp/reviewboard.mysql.dump > > New system (separate host, don't want to risk in place upgrade) > ============================================== > Minimal install of CentOS 6.5 > Add EPEL repo > yum install ReviewBoard mysql-server memcached system-config-firewall-tui > Setup mysql user and create fresh "reviewboard" database. > rb-site install <path> > Drop mysql "reviewboard" database. > Copy mysql dump from old system > Import database: mysql -p reviewboard < reviewboard.mysql.dump > rb-site upgrade <path> > > The upgrade works, the old reviews and users are present.
