Next step is to run the Upgrade.
Step 1: Upgrade you IT Infrastructure
Your IT Support Partner suggests upgrading to the latest version owing to the plethora of new functionality supported by it. Question: Have you discussed the expected increase on loading of your existing IT Infrastructure correspondingly?
Check out the minimum System Requirements Suggested by Oracle for the new Siebel Version that you are upgrading to. Don’t be afraid to factor in something extra. They are only the MINIMUM set of requirements, not the ideal ones!
After upgrading the Hardware, Upgrade the Siebel Enterprise Server to the new release. In the process, it also generates some files relevant in future steps of the Upgrade.
Step 2: Perform Pre-Upgrade Tasks
Prepare the Siebel Database for upgrade. Includes closing all Database Connections, Clearing pending Workflow Tasks, Disabling Custom Triggers, among others.
Step 3: Prepare Application Data
Prepare some Test Data for Migration. It is always smart to use only a small subset covering all major functionalities rather than the humongous Database that most organizations house today. You would obviously need to run the various tasks many a times over during the Upgrade, trying hit and trial in many of the cases. Time is precious. Save it!
Step 4: Siebel Database Upgrade (Upgrep)
Database Configuration Utility is one of the Best friends a Siebel Admin can have. Run it in the “Upgrep” mode. This performs a basic Upgrade of the Siebel Database Schema. Also, it loads the repositories to prepare for Repository Merge.

In the Upgrade process, don’t forget to check the Upgrade path with oracle. This would ensure that you can seamlessly upgrade your present version to the desired Siebel version.
Note: Oracle provides various upgrade paths for vertical and horizontal applications. Based on your assessment, you might be required to downgrade your application to one of the maintenance release supported by Oracle under an Upgrade path. Nonetheless this requirement would not fit for most upgrades but worth a try.
