Hi,

We've been running UAA 3.6 on production and need to upgrade to 3.12. One requirement is that we will need to retain the validity of the token that was issued by UAA 3.6 after the upgrade.

We used the default key for token signing in 3.6, in the upgrade we will use a new key, so I like to know the way how the client be able to verify the signature of the old valid tokens while the new tokens will be signed by a new key after upgrade to 3.12?

Thanks, Sam
