I did the upgrade in my lab environment without any issues. For upgrading productive environments, please consider those points:
- manually configured channel 132 needs to be changed before upgrading
- if NAT and “Extend VSC egress subnet to VSC ingress subnet” are both enabled, NAT will be disabled after upgrading
- MSM710 is not supported by this release
- MSM335 is not supported by this release
