How Do I Enable the SYNC and PSYNC Commands?

Migration within DCS:
- If the online migration task uses the same account and region as the source instance, select a DCS instance (cloud Redis) as the source. The SYNC and PSYNC commands will be automatically allowed on the source instance.
- If the online migration task uses a different account or in a different region from the source instance, the source instance cannot be a DCS instance (cloud Redis) and the SYNC and PSYNC commands are disabled on the source instance. In this case, online migration on the console is unavailable. You can migrate data using backup import.
- By default, the SYNC and PSYNC commands can be used when self-hosted Redis is migrated to DCS.
Migration from other cloud vendors to DCS:
- Generally, cloud vendors disable the SYNC and PSYNC commands. If you want to use the online migration function on the DCS console, contact the O&M personnel of the source cloud vendor to enable the commands. For offline migration, you can import backup files.
- If incremental migration is not required, you can perform full migration by referring to Migrating from Another Cloud Online Using redis-shake. This method does not depend on SYNC and PSYNC.
