How to tell if Database Certificate Used?
This will provide details about the certificates encrypting any database that has TDE encryption enabled:

use master 
select 
    db_name(db.database_id) DatabaseName,
    c.name,
    * 
from sys.databases db
join sys.dm_database_encryption_keys dek
    on
    dek.database_id=db.database_id
join sys.certificates c
    on
    dek.encryptor_thumbprint=c.thumbprint
where
    db.is_encrypted=1


For all other column level encryption within a user database, backup the Database Master Key, migrate it to the other environment and restore it after restoring the user database.
