Looking through the docs n’ stuff, this is what I found:

• Updating Guide. Just basic steps, similar to what I explained above; but with commands to run.
• [docs.paperless-ngx.com/administration/#migrating-…](Backing up and restoring)
• [docs.paperless-ngx.com/changelog/#paperless-ngx-2…](2.0.0 Change Log). Unfortunately they don’t include any notes about how to upgrade

I wasn’t able to find any additional instructions on how to update other than the expected generic steps (docker pull or pip install -r requirements.txt). So my guess at this point is that they have scripts built in to check the version and run upgrade scripts as needed
