Hi Raj,
check Empower or TechCommunity for the appropriate migration guides.
You should consider a side by side migration.
Be careful with webServices as the handling in 9.x is quite different then in 8.2 (not all of our webservice could be migrated directly, instead whe had to read in some of them from scratch and use them with 9.x-handling instead of the old handling. Check the pre-8.2-compatibility. In the some cases we had to correct the WSDL and convince our partners to adopt this on their side).
For the JDBC-Adapter:
check if you can switch the JDBC-Adapter from 6.5 to 9.0.
For the client Adapter:
check if it can be replaced by SAP-Adapter 7.1 or if it needs to be ported to the new ART-version.
For the Broker to UM migration:
From 9.8 there will be a migration Script for this.
If you are still unsure you should contact your responsible SAG consulting department and ask for migration support. They can also give advice about the client adapter.
Regards,
Holger
