Migrating data from one data source to another poses significant risks, including data loss and downtime. However, businesses must innovate to survive, often by moving data into new databases like Redis for real-time capabilities. To take advantage of Redis Enterprise's power, companies can migrate their data from Redis Open Source with the help of Redis Enterprise, which offers infinite linear scalability, high availability, security, and low costs. The key feature that enables zero-downtime database migration is Active-Passive Geo-Distributed Replication, also known as Replica Of, which allows for read-only access to replicas in different geographical locations. This process involves assigning a destination database as a replica of one or more source databases, synchronizing data between them, and distributing the read load across multiple databases. Additionally, Redis Enterprise offers Active-Active Geo-Distribution (CRDB) for write access, ensuring seamless database migrations with real-time capabilities.
