How Do I Enable the SYNC and PSYNC Commands?

Migration within DCS:
- By default, the SYNC and PSYNC commands can be used when self-hosted Redis is migrated to DCS.
- During online migration between DCS Redis instances in the same region under the same account, the SYNC and PSYNC commands are automatically enabled.
- During online migration between DCS Redis instances in different regions or under different accounts within a region, the SYNC and PSYNC commands are not automatically enabled, and online migration cannot be used. You can migrate data using backup files.
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 Online Full Migration of Redis from Another Cloud with redis-shake. This method does not depend on SYNC and PSYNC.
