Migration of Tencent Cloud Distributed Cache to a self-built database
Supports migration between different architectures, including standard architecture > standard architecture, standard architecture > cluster architecture, and cluster architecture > cluster architecture. However, heterogeneous migration (e.g., standard architecture > cluster architecture) may have compatibility issues. For common compatibility issues, see Check on Migration from Standard Architecture to Cluster Architecture.
Standard architecture refers to self-built standalone versions, primary-secondary modes, and Tencent Cloud Distributed Cache Memory Edition (Standard Architecture). Cluster architecture includes Redis Cluster native solutions, Codis cluster solutions, and Twemproxy cluster solutions.
