Login Page not getting Displayed after 10.1.3 Home Upgrade in R12

Question

Hi,
We are performing an Upgrade of 12.0.6 to 12.1.1.
We have just finished the upgrade of 10.1.3 Home to 10.1.3.4. After the successful completetion of Patchset Installation, as a part of Instance
Validation , we found that we were not able to get the R12 Login Page displayed.
On Checking the Apache Logs, The Error Message looked as below:
[Tue Jun 30 03:08:36 2009] [error] [client 159.182.123.2] [ecid: 1246345716:168.146.11.159:585784:0:2,0] File does not exist:
/u18/app/HUTLcomn/apps/HUTL_oldtut353/portal/OA_HTML/AppsLocalLogin.jsp
But AppsLocalLogin.jsp in our environment is located in the correct location
$OA_HTML
oldtut353:orapps(app):HUTL:[home/orapps] echo $OA_HTML
/u18/app/HUTLcomn/webapps/oacore/html
oldtut353:orapps(app):HUTL:[home/orapps] cd
$OA_HTML
oldtut353:orapps(app):HUTL:[u18/app/HUTLcomn/webapps/oacore/html] ls -ltr AppsLocalLogin
-rw------- 1 orapps dba 4094 Jun 16 02:03 AppsLocalLogin.jsp
It is reading the AppsLocalLogin.jsp from a non existent Location < INST_TOP>/portal/OA_HTML/AppsLocalLogin.jsp
I have run the autoconfig successfuly in all the Application Tiers and generated Product JAR Files. But still the Error Exists.
Please help to resolve this issue.

Thank You Helios.
The thread which you had mentioned in your previous reply had the similar issue which i was facing.
I moved forward with the remaining Pre-Upgrade Tasks, Applied Maintainence Pack and then completed the Post Upgrade Tasks.
I am very delighted to let you know that my Upgrade from 12.0.6 to 12.1.1 was successful. I got the feeling of GLADIATOR :) when I saw the Login Page appearing for the first
time after the Upgrade.
Thank you all for your help and Support.
Thanks,Varun
