About Upgrading Data to a Higher Encryption Level

The Encryption Upgrade utility (encryptupg.exe), located in the bin subdirectory of the Siebel Server directory, allows you to do the following:

• Upgrade encrypted data to a higher encryption level, for example, from RC2 (56 bits) to AES encryption, provided you use Siebel Strong Encryption.

  For information on Siebel Strong Encryption, see About Siebel Strong Encryption.

• Upgrade data that was encrypted using the standard encryptor to the AES encryption method.

  NOTE:  You must upgrade data that was encrypted using the standard encryptor (based on the mangle algorithm) to a higher level of encryption before you upgrade to a Siebel CRM version 8. For additional information, see Requirements for Upgrading to a Higher Encryption Level.

In Siebel CRM releases earlier than release 7.5.x, data was encrypted using the standard encryptor. As of Siebel CRM version 7.5.x, Siebel Business Applications use the AES encryption algorithm to encrypt data, and the standard encryptor is supported for backwards-compatibility purposes only. For Siebel CRM version 7.5.3 or higher, you must use AES encryption.

If you want to upgrade encrypted data from Siebel CRM version 6.x or 7.0.x to Siebel CRM version 7.5.3, 7.7, or 7.8, then it is recommended that you upgrade the encrypted data to the AES standard to make sure that the data can be read accurately by the later release. If you want to upgrade encrypted data from Siebel CRM version 6.x or 7.0.x to any Siebel CRM version 8 release, then you must upgrade the encrypted data to the AES standard.

NOTE:  You cannot upgrade directly from a Siebel CRM release earlier than 7.5.x to Siebel CRM version 8.x. If you want to upgrade from Siebel CRM version 6.x, then you must first upgrade to Siebel CRM version 7.7, even if you want to upgrade to a Siebel CRM release later than version 7.7.
