Check Details
The migration from Redis to TencentDB for Redis is supported for source Redis 2.2.6 or later. The migration from Redis to TencentDB for KeeWiDB is supported for source Redis 4.0. To migrate to other versions, submit a ticket for application.
The target database version must be later than or equal to the source database version; otherwise, an alarm will be triggered for compatibility problems during verification.
The target database must have the latest proxy.
Troubleshooting
If the source or target database version is not supported, upgrade the target database version or use a database instance on a higher version.
