We are trying to upgrade the database from 11g to 18c. The wallet master key has been stored in HSM and the auto-login enabled in 11g Database. The wallet is opening in 11g Database without any issues. But, it is complaining that "Wallet-is-not-open" in 18C Database.

Here are the additional details, let me know if any questions or need more information, thanks.
