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 Redis databases from AWS ElasticCache or from other DigitalOcean database clusters.
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 an existing database, you need the following information about the source database:
Reference your database provider’s documentation for details on how to locate this information.
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.
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.
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.
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.
During migration, you can still write to the target database, but avoid the following actions because they may result in conflicts and replication issues:
