Question About Siebel Compatibility During AIA Upgrade From 11g To 12.2

(Doc ID 2387504.1)

Last updated on JUNE 29, 2018

Applies to:

Oracle Communications Order to Cash Integration Pack for Oracle Communications Billing and Revenue Management - Version 12.2.0.0.0 and later
Information in this document applies to any platform.

Goal

Qn1:  On 12.2.0.0.0 version ; The scenario here is an upgrade plan of the Oracle communications suite especially of Oracle Application Integration Architecture (AIA) for Oracle Communications from 11g to 12.2.

As per Compatibility Matrix documentation, it states that Siebel CRM IP 2014 + SP1 is required when upgrading Oracle AIA to version 12.2.

However, a customer might plan to upgrade AIA first, before going ahead with the Siebel upgrade as this will be more extensive than the AIA upgrade.

With the existing version of Oracle Siebel SIA 8.1.1.8, is it possible to upgrade AIA to 12.2 and maintain full functionality with the current Siebel version while the Siebel upgrade is developed and executed later ? Or must both systems forcefully be upgraded at the same time ?
 
Qn2: In context of the above question, a customer is exploring to develop a temporary solution for integration with Siebel (old version) until it is upgraded. As far as SOAP communication goes this does not seem like it will be a problem, since one should be able to adapt the older integration that are already in place, as a workaround.

But the question though is regarding the wlthint3client.jar that must be installed in Siebel. Since this component is provided by AIA with no customization to it, and it seems that is a key component in integration between Siebel and Weblogic, one might want to know if the new version of this component can be deployed on the older Siebel, or if the old version version that is already present (from AIA 11.1.1.6.0) can be used to communicate with the new AIA.

Following documentation is being referenced for the trial runs of AIA Deployment, please see "Setting JVM Parameters for Siebel CRM" on the Post Upgrade tasks:
