[gauth] Google Auth - how to migrate data from cas5.3 to cas6.3

[He Vincent]

Hi all

Google Auth record format has changed in cas6.3, It prevented me from upgrading to cas6.3.

Is there anyway to migrate Google Auth data from cas5.3 to cas6.3?

How can we exort the data and import them to cas6.3?

I sent a few day to study souce code, I found it is using below 2 keys to encode and decode the secret keys:
cas.authn.mfa.gauth.crypto.encryption.key

cas.authn.mfa.gauth.crypto.signing.key

Just keep those 2 parameters same.
