Cisco SD-WAN Minor version upgrade

[RS19]

This is regarding upgrading Cisco SD-WAN for minor releases.

I would like to know what are the steps , sequences, recommendations that needs to be followed when upgrading the vManage, vBond/vSmart & the cEdges.

Is it always required to upgrade all the 3 components for minor releases or is it possible to upgrade vBond/vSmart & vManage only & not upgrading the cEdges. 

Please let me know the right procedure & the sequences.

In addition to the above, wanted to check is there any difference in the procedure between the major version & minimum version upgrade.

All controller should be upgraded to be on the same version according to the procedure described in this guide: https://www.cisco.com/c/en/us/support/docs/wan/dpt/220424-upgrade-sd-wan-controllers-with-the-use.html

For version compatibility you should check the compatibility matrix relevant for your version here: https://www.cisco.com/c/en/us/td/docs/routers/sdwan/release/notes/compatibility-and-server-recommendations.html

Upgrading major and minor version should be the same procedure, but read through the release notes for supported upgrade paths and if there are any important notes.
