# Immich {#module-services-immich}
|
|
|
|
[Immich](https://immich.app/) is a self-hosted photo and video management
|
|
solution, similar to SaaS offerings like Google Photos.
|
|
|
|
## Migrating from `pgvecto-rs` to VectorChord (pre-25.11 installations) {#module-services-immich-vectorchord-migration}
|
|
|
|
Immich instances that were setup before 25.11 (as in
|
|
`system.stateVersion = 25.11;`) will be automatically migrated to VectorChord.
|
|
Note that this migration is not reversible, so database dumps should be created
|
|
if desired.
|
|
|
|
See [Immich documentation][vectorchord-migration-docs] for more details about
|
|
the automatic migration.
|
|
|
|
After a successful migration, `pgvecto-rs` should be removed from the database
|
|
installation, unless other applications depend on it.
|
|
|
|
1. Make sure VectorChord is enabled ([](#opt-services.immich.database.enableVectorChord)) and Immich has completed the migration. Refer to the [Immich documentation][vectorchord-migration-docs] for details.
|
|
2. Run the following two statements in the PostgreSQL database using a superuser role in Immich's database.
|
|
|
|
```sql
|
|
DROP EXTENSION vectors;
|
|
DROP SCHEMA vectors;
|
|
```
|
|
|
|
- You may use the following command to run these statements against the database: `sudo -u postgres psql immich` (Replace `immich` with the value of [](#opt-services.immich.database.name))
|
|
|
|
3. Disable `pgvecto-rs` by setting [](#opt-services.immich.database.enableVectors) to `false`.
|
|
4. Rebuild and switch.
