Data Migration Overview
The DCS console supports online migration (in full or incrementally) and backup migration (by importing backup files) with intuitive operations.
- Backup migration is suitable when the source and target Redis instances are not connected, and the source Redis instance does not support the SYNC and PSYNC commands. To migrate data, import your backup files to OBS, and DCS will read data from OBS and migrate the data to the target DCS Redis instance.
- Online migration is suitable when the source Redis instance supports the SYNC and PSYNC commands. Data in the source Redis instance can be migrated in full or incrementally to the target instance.
For more information about migration tools and schemes, see Migration Tools and Schemes.
