Overview

After upgrade of DIS server to  newer version, face templates generate in lower versions are not compatibile with new ones.


Symptoms

Face matching  is not working when using templates generated in different dis server versions.


Environment

DIS server


Root Cause

Face templates are not backward compatible.

If you need to perform face matching at a later stage, it is recommended that you also store face images in a database. Then, after upgrading to a newer version of DIS with different templates version, these images can be used to generate new templates.
