Can S series modular switches of different versions establish a cluster

2

CSS technology provides an automatic software loading mechanism. Member switches do not have to run the same software version, and they can set up a CSS as long as the software versions running on the member switches are compatible with one another. If software version running on the standby switch is different from that on the master switch, the standby switch downloads the system software from the master switch, restarts with the new system software, and joins the CSS again.

Clusters or stacks of S series switches
A stack or cluster of S series switches is a logical switch consisting of multiple stacking-capable or clustering-capable S series switches. In V200R001C00 and earlier versions, S series switches only set up stacks. In later versions, S series fixed switches set up stacks, and S series modular switches set up clusters. Please ask questions about specific switch models. The following information is possibly related to your question:

Whether the cluster on S series modular switches needs a license
For S7700 and S9700 series switches, licenses are not required for CSS card and service port clustering. Licenses are not required for S12700 clustering. For S9300 series switches, licenses are not required for CSS card clustering, but required for service port clustering.
