You can choose to build with new hardware, or evict the nodes in an existing Windows cluster, reload/upgrade the system and add them to the new Windows cluster. Specific cluster upgrade plan I'm not here to discuss it. Immediately enter the topic: One requirement of

generally cannot be used for high availability. Image: the master-slave mode, single-active (the secondary machine is not readable), and hardware resources are wasted. The main scenario is the high availability of databases. Compared with the Failover cluster image, it is highly available at the database level. In an image, you can use snapshots to separate read/write data. Log transmission: it is mainly used for disaster recovery and can be read on the backup machine. However, the disadvantage
