Install updates

As root:

/edx/bin/update edx-platform release

Upgrade procedure

• put up a ‘down for maintenance’ message
• make sure the original server is accessible to you (public must not be able to make changes); might need to close any existing connections
• take a snapshot using LXC (have to take down the server to do this); also verify that the snapshots can be restored if things go badly
• perform the upgrades
• verify that upgrades are working correctly
• remove the ‘down for maintenance’ message
• LATER: remove any snapshots once you’re sure that they’re not needed
  • List LXC snapshots with lxc-snapshot -L -n <container name>

Update database tables

On Devstack:

paver update_db -s devstack

In production:

ubuntu@edxprod:/edx/app/edxapp/edx-platform$ sudo -u www-data /edx/bin/python.edxapp ./manage.py lms migrate --settings=aws
