Replication of a collection from a non-clustered node

[DubovskoySergey]

Hello,

We are just starting to work with Qdrant. Our instance is running in single mode in a Docker container, so all collections were created with the parameters shard_number=1 and replication_factor=1.

We want to migrate all the data to a Qdrant cluster deployed in Kubernetes. From the documentation, I understand that when restoring a snapshot on a new node, our parameters shard_number=1 and replication_factor=1 will prevent the system from replicating data across nodes. I also found in the API documentation the Replicate Shard Operation method, which allows copying a shard from one node to another, with the new shard retaining the original shard's ID and being marked as Recovery. If I use the update_collection method to increase the replication_factor, the new shard is marked as Active, but its ID still matches the original.

Could you please advise whether replication will work in this scenario? Or is recreating the collection unavoidable?

Thank you.
