Migrate Open edX

NOTE: Before proceeding to migrate the Bitnami edX stack, ensure that you have performed a complete backup.

Migrate edX

Log in to your edX instance and follow the steps below:

• Create a directory where to store all the data:

  $ mkdir edx-migrate-data
  

• Dump databases required by edX:

  • MySQL:

    $ /opt/bitnami/mysql/bin/mysqldump -u root -p --databases bitnami_edxapp bitnami_edxapp_csmh bitnami_xqueue --add-drop-database > edx-upgrade-data/bitnami_edx_mysql.sql
    

  • MongoDB:

    $ /opt/bitnami/mongodb/bin/mongodump --authenticationDatabase admin -h localhost -u root -d bitnami_edxapp --out edx-upgrade-data/bitnami_edx_mongodb
    $ /opt/bitnami/mongodb/bin/mongodump --authenticationDatabase admin -h localhost -u root -d bitnami_cs_comments_service --out edx-upgrade-data/bitnami_edx_mongodb
    

• Copy edX Platform configuration and data files (which contain uploads, courses, etc.). The commands below also clear the assets to reduce the size of the directory:

  $ cp /opt/bitnami/apps/edx/conf/*.json edx-migrate-data
  $ cp -R /opt/bitnami/apps/edx/var edx-migrate-data
  $ rm -rf edx-upgrade-data/var/staticfiles/*
  

• Copy edX XQueue configuration files:

  $ cp /opt/bitnami/apps/edx/conf/*.json edx-migrate-data
  

• Copy edX Forum configuration files:

  $ cp /opt/bitnami/apps/forum/conf/httpd-forum.conf edx-migrate-data
  

• Compress the generated files:

  $ tar czf edx-migrate-data.tar.gz edx-migrate-data
  

• Copy edx-migrate-data.tar.gz over to the new edX instance.

Next, log in to the new edX instance and navigate to the directory where you copied edx-migrate-data.tar.gz. Then, proceed with the following steps:

• Extract the compressed file:

  $ tar xzf edx-migrate-data.tar.gz
  

• Migrate databases:

  • MySQL:

    $ /opt/bitnami/mysql/bin/mysql -u root -p < edx-upgrade-data/bitnami_edx_mysql.sql
    

  • MongoDB:

    $ /opt/bitnami/mongodb/bin/mongorestore --authenticationDatabase admin -h localhost -u root --drop -d bitnami_edxapp edx-upgrade-data/bitnami_edx_mongodb/bitnami_edxapp
    $ /opt/bitnami/mongodb/bin/mongorestore --authenticationDatabase admin -h localhost -u root --drop -d bitnami_cs_comments_service edx-upgrade-data/bitnami_edx_mongodb/bitnami_cs_comments_service
    

• Migrate edX Platform data:

  • Replace the edX Platform data directory with the one copied from your previous edX installation:

    $ sudo rm -rf /opt/bitnami/apps/edx/var
    $ sudo cp -R edx-migrate-data/var /opt/bitnami/apps/edx/var
    $ sudo chown -R daemon:daemon /opt/bitnami/apps/edx/var
    

  • (Optional) Review edX Platform configuration for custom changes in the previous installation (e.g. themes, SMTP configuration, etc.):

    • LMS configuration files: /opt/bitnami/apps/edx/conf/lms.auth.json and /opt/bitnami/apps/edx/conf/lms.env.json.
    • CMS configuration files: /opt/bitnami/apps/edx/conf/cms.auth.json and /opt/bitnami/apps/edx/conf/cms.env.json.

  • Run edX Platform migrations:

    $ sudo /opt/bitnami/apps/edx/bin/edxapp-migrate-lms
    $ sudo /opt/bitnami/apps/edx/bin/edxapp-migrate-cms
    

  • Update assets for edX Platform:

    $ sudo /opt/bitnami/apps/edx/bin/edxapp-update-assets-lms
    $ sudo /opt/bitnami/apps/edx/bin/edxapp-update-assets-cms
    

• Migrate edX XQueue data:

  • (Optional) Review XQueue configuration for custom changes in your previous installation: /opt/bitnami/apps/xqueue/conf/xqueue.yml.

    NOTE: Since edX Hawthorn, a couple of major changes have happened: The XQueue configuration files xqueue.auth.json and xqueue.env.json have been merged into xqueue.yml, and it does not use RabbitMQ anymore.

  • Run edX XQueue migrations:

    $ sudo /opt/bitnami/apps/xqueue/bin/django-admin.xqueue migrate --noinput
    

• Restart Apache, edX Celery Workers and XQueue:

  $ sudo /opt/bitnami/ctlscript.sh restart apache
  $ sudo /opt/bitnami/ctlscript.sh restart edx
  $ sudo /opt/bitnami/ctlscript.sh restart xqueue
  

Your Bitnami edX stack should now be fully migrated. Confirm that the migration was successful by logging into edX and verifying the integrity of your data.
