Upgrade from 4.0.22 to 4.2.5 - OCR, Parsing etc. not working anymore

Post by bernroth »

Dear Community!

We recently upgraded our Mayan EDMS installation (based on docker-compose) from 4.0.22 to 4.2.5.
This will be the last "issue" to report for the meantime.

After fixing the sources, documents are getting imported and shown in the "Recently created" section.
Unfortunately there is no "Content" (OCR data) available.
Options like "delete parsed content", "submit for parsing" are not working.

While watching the logs I found suspicious errors like

Code: Select all

I think maybe the best approach to fix those issues is to delete all OCR data and caches and recreate all together.

I only like to keep:

- documents
- tags
- cabinets

... and recreate all other data from the scratch.
Given the amount of data, this will probably take weeks to complete but then - hopefully - no more weird error messages in the log anymore.

Is there maybe any other possibility to address those issues?
