# Unfollow an index

**POST /{index}/_ccr/unfollow**

Convert a cross-cluster replication follower index to a regular index.
The API stops the following task associated with a follower index and removes index metadata and settings associated with cross-cluster replication.
The follower index must be paused and closed before you call the unfollow API.

> info
> Currently cross-cluster replication does not support converting an existing regular index to a follower index. Converting a follower index to a regular index is an irreversible operation.
