Siebel Security Guide > Communications and Data Encryption > About Upgrading Data to a Higher Encryption LevelThe Encryption Upgrade utility (encryptupg.exe), located in the bin subdirectory of the Siebel Server directory, allows you to do the following:
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 and the RC2 encryption algorithms 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 either AES or RC2 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 RC2 or 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 RC2 or 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. |
