We are going to discuss some important aspects of Siebel CRM upgrade after version 25.5.

Beside the key functional innovations as is AI and Intelligence,Customer 360 and Digital Business Experience, Integrations and API, Cloud Operations there are also architectural innovations such as Tomcat upgrade to 10 and Java upgrade to Java 21. This includes also new AES 256 encryption and migration of all libs using javax.

We as a integration partner and CRM consultancy have experience in this process and can guide you and do for you this complex upgrade.

You will need to review

all in the internal tomcat /config agent/ libs which are custom for different purposes and review whether javax is used and reimplement and recompile these for compatible java 21 jakarta classes
all tomcat external customization libs for webserver also need to be reimplement and recompiled for the java 21 supported jakarta.* instead of javax.*
review also jms typical clients and use java21 compatible ones
have all passwords encrypted
review all trustores and keystores whether they have valid certficate usage /clientauth and serverauth/. Java 21 is very strict for extended usage of the certificates, they need to be appropriate
