From Redis	Migrate Redis vector data out of RediSearch full-text indexes and into Qdrant for a dedicated vector search backend.	Migrate from Redis to Qdrant by streaming vectors and metadata out of RediSearch FT indexes and into Qdrant collections with the Qdrant Migration Tool.	70

Migrate from Redis to Qdrant

What You Need from Redis

• Redis address — host and port of your Redis instance
• FT index name — the RediSearch full-text index that contains your vectors
• Authentication — username and password, if configured

Important: Redis does not expose vector configurations (dimensions, distance metric) after an index is created. You must create the Qdrant collection manually before running the migration.

Concept Mapping

Redis	Qdrant	Notes
FT Index	Collection	One-to-one mapping
Document	Point	Each document becomes a point
Vector field	Vector	Named vectors are preserved
Hash/JSON fields	Payload	Direct mapping
Document key	Payload field	Stored via --qdrant.id-field

Run the Migration

docker run --net=host --rm -it registry.cloud.qdrant.io/library/qdrant-migration redis \
    --redis.index 'your-ft-index' \
    --redis.addr 'localhost:6379' \
    --qdrant.url 'https://your-instance.cloud.qdrant.io:6334' \
    --qdrant.api-key 'your-qdrant-api-key' \
    --qdrant.collection 'your-collection'

With Authentication

docker run --net=host --rm -it registry.cloud.qdrant.io/library/qdrant-migration redis \
    --redis.index 'your-ft-index' \
    --redis.addr 'your-redis-host:6379' \
    --redis.username 'your-username' \
    --redis.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 Redis-Specific Flags

Flag	Required	Description
--redis.index	Yes	RediSearch FT index name
--redis.addr	No	Redis address (default: localhost:6379)
--redis.protocol	No	Redis protocol version (default: 2)
--redis.username	No	Username for authentication
--redis.password	No	Password for authentication
--redis.client-name	No	Client name
--redis.db	No	Database number
--redis.network	No	Network type: tcp or unix (default: tcp)

Qdrant-Side Options

Flag	Default	Description
--qdrant.id-field	__id__	Payload field name for original Redis document keys

Gotchas

• Named vectors: If your Redis index has multiple vector fields, all are migrated as named vectors. Ensure your pre-created Qdrant collection has a matching named vector configuration.
• ID mapping: Redis document keys are converted to Qdrant point IDs. The original key is stored in the payload under --qdrant.id-field.

Next Steps

After migration, verify your data arrived correctly with the Migration Verification Guide.
