How Does MgC Generate Target Redis Recommendations?

The following table describes how the system recommends Redis versions and specifications during assessment.

**Table 1** Recommended specifications for different Redis instances
Source	Instance Type	Version	Instance Specifications
Huawei Cloud	The lift-and-shift migration policy is followed, and the target instance specifications match the source instance specifications.
Other clouds	The target instance architecture is mapped to the source instance architecture. Single-node, master/standby, read/write splitting, Proxy Cluster, and Redis Cluster instances are matched with their respective equivalents. This ensures architecture consistency, uniform access modes, and service compatibility, preventing function, performance, and protocol compatibility issues caused by architecture differences after the migration.	If the rounded-down source version is less than or equal to 4, the target version is 4.0. If the rounded-down source version is 5, the target version is 5.0. If the rounded-down source version is greater than or equal to 6, the target version is 6.0.	Target specifications are matched 1:1 with source specifications. If an exact match is unavailable, the system recommends the next higher specifications that are closest to the source.

Any missing key fields may cause the Redis assessment process to fail. The following table describes the fields required for Redis assessment.

**Table 2** Fields required for Redis assessment
Required Field	Field Description
Instance architecture	Redis instance deployment architecture, type, and version After the collection is complete, this information can be viewed and obtained from the Source Version \| Instance Type \| Memory \| Shards column in the resource list.
Version	Redis instance version. After the collection is complete, this information can be viewed and obtained from the Source Version \| Instance Type \| Memory \| Shards column in the resource list.
Instance specifications	Redis instance specifications. After the collection is complete, this information can be viewed and obtained from the Source Version \| Instance Type \| Memory \| Shards column in the resource list.
