Why Do I need to Move the database to a different Instance
Moving or restoring an TDE eanbled encrypted database could be of different reason.
IMPORTANT Please Be advised that if a database is encrpted by TDE ans associated with a key and a cetificate it needs to have both the key and cetificate to
If we look at the previous page I have a database named 'xxxvi' in my instance for which TDE is enabled.
now if you want to transport the database to a different server or instance and try to restore it just doesnt allow you to restore Hence you need to follow the below steps
To make it easier I have created a folder named backup on "D" drive and moved The files from the previous instance to the current instance.
The files I moved are
My files location is as follows
Step 1: Create master key on the new instance where the database needs to be restored
USE master GO CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'NeP@$$w04#' GO -- we have created a Master Key in the New instance
Step 2: Create certificate from the previously saved certificate
CREATE CERTIFICATE XXXVI_DB_Cert WITH SUBJECT = 'XXXVI_DB_Certificate'; GO -- we have created a certifcate now
Step 3: Restoring the credentials
USE master GO CREATE CERTIFICATE XXXVI_DB_Cert FROM FILE='D:\Backup\XXXVI_DB_Cert.cer' WITH PRIVATE KEY( FILE='D:\Backup\XXXVI_DB_Cert_Key.pvk', DECRYPTION BY PASSWORD='XXXVIT3stD@8@Pw6') GO --I am using a different password here
Step 4: Restoring the Database
USE master GO RESTORE DATABASE [XXXXVI] FROM DISK = N'D:\Backup\XXXVI.bak' GO
Step 5: Verification
--Check Certificates USE master GO SELECT *FROM sys.certificates WHERE pvt_key_encryption_type <> 'NA' GO --Check Encryption Key Details for 2008 USE master GO SELECT key_length, key_algorithm, encryption_state, create_date FROM sys.dm_database_encryption_keys GO --Check Encryption Key Details for 2012 and further versions USE master GO SELECT encryptor_type, key_length, key_algorithm, encryption_state, create_date FROM sys.dm_database_encryption_keys GO
