Upgrade Oracle 9iAS release 1(1.0.2.2.x) to AS 10g release 3 (10.1.3.4)

There is no direct upgrade path from Oracle9iAS Rel 1 to OracleAS 10g. Furthermore, there are no white papers or support articles which discuss upgrading Oracle9iAS Rel 1 to OracleAS 10g. This is because Oracle9iAS Rel 1 was desupported on 30th June 2004 and the first production release of OracleAS 10g - OracleAS 10g Rel 2 (10.1.2.0.0) was not in shipping until January 2005. 

 

For Apps instances, it is well documented in metalink notes

and 233436.1: Installing Oracle Application Server 10g with Oracle E-Business Suite Release 11i

For non-apps instances, our approach is to upgrade first to Oracle 9iAS Release 2 and then upgrade from this version to OracleAS 10g Rel 1 which is finally upgraded to Oracle AS 10g Release 3.  Here's a list of high level steps:

 

Task 1: Install the Oracle 9iAS Release 2

 

Task 2: Use the Oracle 9iAS Migration assistant to migrate Oracle HTTP Server, 9i AS containers for J2EE and webcache

 

Task 3: Perform any manual tasks necessary to complete the upgrade of these compoents

 

Task 4: Install AS 10g Release 1(9.0.4) infrastructure services

 

Task 5: Install the Oracle Application Server 10g (9.0.4) middle tier

 

Task 6: Use OracleAS Upgrade Assistant to upgrade HTTP Server, containers for J2EE and Web Cache

 

Task 7: Perform any manual upgrade tasks necessary to complete the upgrade of each component.

            

Task 8: Determine an AS 10g Release 3 (10.1.3.4) topology to install and configure

 

Task 9: Install and Configure 10g AS release 3 environment

 

Task 10: Perform any required pre-deployment tasks like configure data sources, resource adapters, http server

           

Task 11: Redeoply your 9i AS applications on AS 10g release 3

 

Task 12: Verify your redeployed applications on AS 10g release 3

 

Task 13: Decommission the 9i AS and AS 10g release  1Oracle Homes.

 

So the upgrade path will be like this:

 

Oracle 9i AS release 1 ----> Oracle 9i AS release 2 ----> Oracle AS 10g release 1 -----> Oracle AS 10g release 3
