How to Migrate Redis Databases

Redis is an open source, key-value database built with an in-memory design that emphasizes speed. It has support for rich data types, atomic operations, and Lua scripting.

You can migrate existing on-premise or cloud hosted Redis databases to clusters in your DigitalOcean account. Migrating a database establishes a connection with an existing database and replicates its contents to the new database cluster. If the existing database is continuously being written to, the migration process will continue until there is no more data to replicate or you manually stop the migration.

We do not currently support migrating managed database clusters on DigitalOcean to other managed database clusters on DigitalOcean. For example, you cannot migrate a managed database cluster from one DigitalOcean account to another.


To migrate an existing database to a DigitalOcean database cluster, you need to reference the source database’s connection credentials and to disable or update any firewalls between the databases.

Before migrating a database, ensure that the source’s Redis version is not newer than the target cluster’s. This can result in an error that causes migration to fail.

Reference Source Database’s Credentials

Before migrating an existing database, you need the following information about the source database:

  • Hostname or connection string - The public hostname, connection string, or IP address used to connect to the database.
  • Port - The port used to connect to the database. DigitalOcean clusters connect on port 25061 by default.
  • Username - The username used to connect to the database. The username should have sufficient permissions to access the data you want to migrate.
  • Password - The password used to connect to the database.

Reference your database provider’s documentation for details on how to locate this information.

Update or Disable Firewalls

To migrate an existing database, you also need to update or temporarily disable any firewalls protecting the databases to allow the databases to connect to each other.

To do this on the target DigitalOcean database, remove any trusted sources from the database cluster. Removing all trusted sources leaves the database open to all incoming connections. To keep your databases secure after migration, make sure to add the trusted sources back to the database.

For the source database outside of DigitalOcean, you may need to update or temporarily disable any firewalls protecting the database before attempting migration. Please refer to your database provider’s documentation to see how to do this.

Migrate a Database Using the API

How to migrate a database using the DigitalOcean API

To migrate a database using the DigitalOcean API, follow these steps:

  1. Create a personal access token, and save it for use with the API.

  2. Send a PUT request to{database_cluster_uuid}/online-migration


    To migrate a database with cURL, call:

                    curl -X PUT \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
    -d '{"source":{"host":"","dbname":"defaultdb","port":25060,"username":"doadmin","password":"paakjnfe10rsrsmf"},"disable_ssl":false,"ignore_dbs":["db0","db1"]}' \


                    import os
    from pydo import Client
    client = Client(token=os.environ.get("DIGITALOCEAN_TOKEN"))
    req = {
      "source": {
        "host": "",
        "dbname": "defaultdb",
        "port": 25060,
        "username": "doadmin",
        "password": "paakjnfe10rsrsmf"
      "disable_ssl": False
      "ignore_dbs": ["db0","db1"]
    update_resp = client.databases.update_online_migration(database_cluster_uuid="a7a8bas", body=req)

Migrate a Database Cluster Using the Control Panel

To migrate a Redis database from the DigitalOcean Control Panel, click Databases and then select the database you want to migrate to from your list of databases.

From the database’s Overview page, click the Actions button and then select Set Up Migration.

Action menu with Set Up Migration highlighted

In the Redis migration window, click Continue, then enter the source database’s credentials. Once you have entered the source database’s credentials, click Start Migration. A migration status banner opens at the top of the Overview page and your target database’s data begins to transfer.

Redis migration with credentials

You can stop the migration at any time by clicking the Stop Migration button in the migration status banner. If you stop migration, the database retains any migrated data.


Migrations automatically stop after two weeks. We do not recommend leaving migrations ongoing in order to keep two database clusters in sync.

During migration, you can still write to the target database, but avoid the following actions because they may result in conflicts and replication issues:

  • Do not manually alter the source database’s replication configuration.
  • Do not make changes to either database that could prevent the source and target database from connecting with each other. This includes updating or enabling firewalls/trusted sources on either database.
