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 unencrypted data to the RC2 encryption method.
• Upgrade encrypted data to a higher encryption level, for example, from RC2 (56 bits) to RC2 (128 bits), provided you have installed the Siebel Strong Encryption Pack.

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

• Upgrade data that was encrypted using the standard encryptor to the RC2 encryption method.

You must upgrade data that was encrypted using the standard encryptor (based on the mangle algorithm) to RC2 encryption before you upgrade to a Siebel version 8 release. For additional information, see Requirements for Upgrading to a Higher Encryption Level.

About the Standard Encryptor

In Siebel CRM releases earlier than 7.5.x, data was encrypted using the standard encryptor. As of Siebel CRM 7.5.x, Siebel Business Applications use the AES and the RC2 encryption algorithms to encrypt data, and the standard encryptor is supported for backwards-compatibility purposes only.

If you want to upgrade encrypted data from Siebel CRM 6.x or 7.0.x to Siebel CRM 7.5.3, 7.7, or 7.8, it is recommended that you upgrade the encrypted data to the RC2 or AES standard to ensure that the data can be read accurately by the later release. If you want to upgrade encrypted data from Siebel CRM 6.x or 7.0.x to any Siebel CRM 8 release, you must upgrade the encrypted data to the RC2 or AES standard. For information on the specific tasks you must perform to upgrade your data to a higher encryption level, see Process of Upgrading Encrypted Data to a Higher Encryption Level.

NOTE:  You cannot upgrade directly from a Siebel CRM release earlier than 7.5.x to release 8.0. If you want to upgrade from release 6.x, you must first upgrade to release 7.7 even if you want to upgrade to a release later than 7.7.
