* initial commit; fixed anchor links on internal docs pages * add back in absolute paths for links in code comments * fix: update linkchecker include filter to match server port 1314 PR #1629 changed the Hugo server to port 1314 but forgot to update the --include filter, which still matched port 1313. This caused all links to be excluded, making the checker a no-op (0 checked, 82277 excluded).

Migrate to Qdrant
The Qdrant Migration Tool is a CLI that moves your vectors, metadata, and sparse embeddings from other vector databases into Qdrant. It runs as a Docker container, streams data in batches, and can resume interrupted migrations.
docker pull registry.cloud.qdrant.io/library/qdrant-migration

General Advice
-
Run the tool close to your databases. Direct connectivity between source and target is not required — the tool streams through the machine it runs on. For best performance, use a machine with low latency to both.
-
Use
--net=hostfor local instances. If either database runs on the host machine, the container needs host networking to reachlocalhost. -
The tool resumes by default. Migration progress is tracked in a
_migration_offsetscollection in Qdrant. If a migration is interrupted, re-running the same command picks up where it left off. Use--migration.restartto force a fresh start. -
Batch size is tunable. The default batch size is 50. For large migrations, increase it with
--migration.batch-size(e.g., 256 or 512) to improve throughput.

After Migration
Once your data is in Qdrant, verify that everything arrived correctly:
