Changes since 0.7.0

Extremely minor change to the documenation links

Upgrading an OpenREM server with no internet access

Follow the instructions found at Upgrade an offline OpenREM installation, before returning here to update the database and configuration.

Upgrading from version 0.6.0

  • Back up your database

    • For PostgreSQL you can refer to Backup the database
    • For a non-production SQLite3 database, simply make a copy of the database file
  • Stop any Celery workers

  • The 0.7.0 upgrade must be made from a 0.6.0 (or later) database, and a schema migration is required:

pip install openrem==0.7.1

In a shell/command window, move into the openrem folder:

  • Ubuntu linux: /usr/local/lib/python2.7/dist-packages/openrem/
  • Other linux: /usr/lib/python2.7/site-packages/openrem/
  • Linux virtualenv: vitualenvfolder/lib/python2.7/site-packages/openrem/
  • Windows: C:\Python27\Lib\site-packages\openrem\
  • Windows virtualenv: virtualenvfolder\Lib\site-packages\openrem\

Delete all numbered migration files in openrem’s remapp/migrations folder, leaving the 0002 files ending in .inactive

  • If there is no file named in the remapp/migrations folder, please create it.
  • If you have accidentally deleted the 0002 files ending in .inactive, you can get a new copy from the bitbucket repository.
python migrate --fake-initial
python makemigrations remapp
python migrate remapp --fake

Now rename the file




and then run

python migrate remapp


With a large database, this may take some time!

  • Review the new openremproject/ file and copy accross the logging section. Then see Log file settings in the install docs.

    If you are using PuTTY on Windows to interact with a linux server, you can select the logging configuration section of the example file with your mouse, and it will be automatically copied to the clipboard. Then open the existing file with nano, move the curser down to the bottom and click the right mouse button to paste.

Restart all the services!

Some of the commands and services have changed - follow the guide at Start all the services.

Upgrading from version 0.7.0 beta 7 or later

  • Stop any Celery workers
  • You will need to do a database migration.
pip install openrem==0.7.1

From the openrem folder (see above):

python makemigrations remapp
python migrate remapp
  • Review the new file and copy accross the logging section. Then see Log file settings in the install docs.
