I have the need to import a database updated to openlca 1.7 scheme back to openlca 1.4, but it tells me that the database is for a newer version of openlca. How can i proceed?

Personally, I haven't tried this before but can you export e.g. product systems in openLCA 1.8 as JSON-LD and import them into an empty DB in openLCA 1.4?

You can export specific database items from openLCA 1.8 as ILCD or EcoSpold and try importing them in openLCA 1.4. Usually, we recommend using JSON-LD when exporting/importing database elements with openLCA. However, JSON-LD was not implemented in openLCA 1.4 yet.

In general, databases are not compatible between openLCA 1.4 and openLCA 1.8. You can reverse the changes via a script. The logic is explained here https://github.com/GreenDelta/olca-updates. You can also hire GreenDelta GmbH to do this for you.
