Migrating EDD from 2.6.x to 2.7.0+

S3 Storage

The 2.7.0 version of EDD introduces use of an S3-compatible storage backend for static assets and media. EDD may continue running with local disk storage, with no changes. If making use of the new storage backend, it is necessary to first migrate existing media / attachment files from the existing storage to the new storage backend.

If you have command-line access to the deployed environment, the easiest way to migrate is to use the mc command-line tool. Using the Docker container, a migration could run like so:

# on old host; replace ${ATTACHMENT_VOLUME} with volume name,
# i.e. edd_edd_attachments
docker pull minio/mc
docker run --rm -it \
    --entrypoint /bin/sh \
    -v ${ATTACHMENT_VOLUME}:/run/attachments \
# inside the mc container
mc alias set minio ${MINIO_ADDRESS} ${ACCESS_KEY} ${SECRET_KEY}
# if bucket does not exist, create it!
mc mb minio/${BUCKET_NAME}
mc policy set download minio/${BUCKET_NAME}/static
mc policy set download minio/${BUCKET_NAME}/media
# mirror command may be repeated
# do a final sync before decommissioning old version deployment
mc mirror /run/attachments minio/${BUCKET_NAME}/media

If you do not have command-line access, and the S3 bucket is already provisioned for you, you may use EDD itself to mirror files. First, deploy EDD with prior storage settings, plus the settings for boto3 storage from Django Storages, and set EDD_ENABLE_S3_MIGRATE = True.

The local settings file should include a section looking something like this:

# purposefully commented out!
# DEFAULT_FILE_STORAGE = "edd.utilities.S3MediaStorage"
STATICFILES_STORAGE = "edd.utilities.S3StaticStorage"

Then, in the admin site, there will be an action item (global) Migrate S3 Storage on the Attachments model. Select any attachment, then run this item, and existing media files will get migrated to the new storage backend.

Once completed, uncomment the DEFAULT_FILE_STORAGE and remove the EDD_ENABLE_S3_MIGRATE line in the local settings. Re-deploy EDD with these settings, to begin serving media files from the S3 bucket instead of prior storage (local Docker volume or host-mounted volume).

Note, because of how the EDD assets are built with Webpack, URLs for static assets must serve those assets with /static/ as the root path. This can be done by adding a vhost configuration file to Nginx like below. When the proxy domain is a local development domain (e.g. *.lvh.me), additionally include both AWS_S3_SECURE_URLS = False and AWS_S3_URL_PROTOCOL = "http:".

location /static/ {
    proxy_pass ${URL_OF_S3_BUCKET}/static/;
location /media/ {
    proxy_pass ${URL_OF_S3_BUCKET}/media/;

Categories for Import / Data Loading

There are four types of Category pre-defined in the updated import in 2.7.0. Choosing a Category limits the list of Protocols and Layouts available during an import. While the built-in supported layouts of “Generic” and “Skyline” are automatically assigned to each Category, there is no automatic assignment of Protocols to Categories. As a result, it is impossible to progress beyond the first step of an Import process; a Protocol must be selected to proceed, and no valid Protocols are available to choose from.

To fix this, an administrator must edit the list of protocols available for each category, in the admin site at /admin/load/category/. It is recommended to add every available Protocol to the Other Category. The Protocols added to Metabolomics, Proteomics, and Transcriptomics should be limited to those individual -omics Protocols.
