Some functionality is not working after I upgraded my system to a new MOS and applied my old brand.
New MOS versions regularly introduce new features or re-architect existing features. Applying a brand from a previous MOS may not work in all instances. Therefore, as per the software release notes, administrators should re-apply branding steps after upgrading a branded system to ensure full functionality.
Detailed steps on how to re-publish a brand are provided in the "Upgrade your brand" section in the MOS Release Notes.
Administrators can download a base factory default brand from the administrator GUI and implement the changes. It is always advisable to apply your customizations to the latest default brand to ensure full functionality.
Using an old brand file, for example from v4.1, on a new major MOS version, for example, v4.2 is not guaranteed to work and is not a supported option. Using a brand file on the same minor version is supported, for example, a brand file from v4.1.2 will work on v4.1.4.
