1. Is this request related to a challenge you're experiencing? Tell me about your story.

I have created KnowledgeBases of different RAG on different self-hosted dify instances. I thought that I could combine the KBs by moving the Volumes folder (dify/docker/volumes) from one machine into the other. This has not worked for me and I am not sure why not. I believe it is because some duplicative files need to come from the source and others need to be from the destination. I cannot figure out which ones come from which source.

There are about 30MB of duplicated files that are mostly in db with five in Weaviate (classifications.db, modules.db, schema.db, and the two migration1.19 filter2search) and one in redis (dump.rdp). The bulk of the duplicated files are in volumes/db/data/pgdata, including bits in base, global, etc.

2. Additional context or comments

I have tried to harmonize versions (Docker, Ollama, Dify, models, etc.) between the instances to no avail.
