Dear Experts,
We are about to do a portal upgrade from 7.1 to 7.4.
In the 7.1 system there are lot of custom applications implemented.
Most of them are J2EE and Java applications.
Also they have custom developed WDJ ESS application and few WDA applications.
Below are my questions
1) what are the details which should be shared with us by the customer
before starting the upgrade process
2) what are the prerequisites should be done before doing the upgrade
3) what are the post upgrade checks should be done after upgrade
Regards,
Parthibaraja
