* 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 from Apache Solr to Qdrant
|
|
|
|
## What You Need from Solr
|
|
|
|
- **Solr URL** — the base URL of your Solr instance (e.g., `http://localhost:8983`)
|
|
- **Collection name** — the Solr collection to migrate
|
|
- **Authentication** — username and password, if configured
|
|
|
|
<aside role="alert"><strong>Important:</strong> Solr does not reliably expose vector dimensions and distance metrics via its schema API. You must create the Qdrant collection manually before running the migration.</aside>
|
|
|
|
## Concept Mapping
|
|
|
|
| Solr | Qdrant | Notes |
|
|
| :--- | :--- | :--- |
|
|
| Collection | Collection | One-to-one mapping |
|
|
| Document | Point | Each document becomes a point |
|
|
| Dense vector field | Vector | Named vectors are preserved |
|
|
| Non-vector fields | Payload | Direct mapping |
|
|
| Document ID (`id` field) | Payload field | Stored via `--qdrant.id-field` |
|
|
|
|
## Run the Migration
|
|
|
|
```bash
|
|
docker run --net=host --rm -it registry.cloud.qdrant.io/library/qdrant-migration solr \
|
|
--solr.url 'http://localhost:8983' \
|
|
--solr.collection 'your-collection' \
|
|
--qdrant.url 'https://your-instance.cloud.qdrant.io:6334' \
|
|
--qdrant.api-key 'your-qdrant-api-key' \
|
|
--qdrant.collection 'your-collection'
|
|
```
|
|
|
|
### With Authentication
|
|
|
|
```bash
|
|
docker run --net=host --rm -it registry.cloud.qdrant.io/library/qdrant-migration solr \
|
|
--solr.url 'https://your-solr-host:8983' \
|
|
--solr.collection 'your-collection' \
|
|
--solr.username 'your-username' \
|
|
--solr.password 'your-password' \
|
|
--qdrant.url 'https://your-instance.cloud.qdrant.io:6334' \
|
|
--qdrant.api-key 'your-qdrant-api-key' \
|
|
--qdrant.collection 'your-collection' \
|
|
--migration.create-collection false
|
|
```
|
|
|
|
### All Solr-Specific Flags
|
|
|
|
| Flag | Required | Description |
|
|
| :--- | :--- | :--- |
|
|
| `--solr.url` | Yes | Solr base URL (e.g., `http://localhost:8983`) |
|
|
| `--solr.collection` | Yes | Solr collection name |
|
|
| `--solr.username` | No | Username for basic authentication |
|
|
| `--solr.password` | No | Password for basic authentication |
|
|
| `--solr.insecure-skip-verify` | No | Skip TLS certificate verification (default: `false`) |
|
|
|
|
### Qdrant-Side Options
|
|
|
|
| Flag | Default | Description |
|
|
| :--- | :--- | :--- |
|
|
| `--qdrant.id-field` | `__id__` | Payload field name for original Solr document IDs |
|
|
|
|
## Gotchas
|
|
|
|
- **Named vectors:** If your Solr schema has multiple dense vector fields, all are migrated as named vectors. Ensure your pre-created collection has matching named vector configurations.
|
|
- **ID mapping:** Solr document IDs (strings) are converted to Qdrant UUIDs. The original Solr ID is stored in payload under `--qdrant.id-field`.
|
|
|
|
## Next Steps
|
|
|
|
After migration, verify your data arrived correctly with the [Migration Verification Guide](/documentation/migration-guidance/).
