Must vManage, vBond and vSmart all run the same OS version?

[modular182]

With SD-WAN, must the vManage, vBond and vSmart all run the same OS version? Or, is it possible to run 19.1.X on vBond and vSmart and 19.2.X on vManage? Thanks!

Hi,

Check the Software Version Compatibility:

"All controller devices of the same type must run the same software version. That is, all Cisco vManage instances must run the same software version, all Cisco vSmart Controllers must run the same software version, and all Cisco vBond Orchestrators must run the same version"

According to the documentation no, but is good to have all the controllers at the same software level to keep your enviroment organized.

Other thing always check that your controllers versions are compatible to the cEdges softwares versions.

If you going to upgrade your enviroment check the Best Practices for Software Upgrades section.
