 Hi, 

We have planned to upgrade from 10.2.0.2 to 11.2.0.3.4 tomorrow.  we have decided to go with fall back plan earlier but in the last minute CLIENT asked me prepare downgrade plan. Any inputs from based on your experience.

 

Following are the pre-cautions i am going to take at this moment.

1) Collect all the DB link information as DOC#837570.1 IN Step 5.

2) Compatible will be retained as old value only.

 

also i have one more doubt for example,

 

if i upgrade to 11.2.0.3 and users does some transactions for one day, then can i downgrade to lower version with loosing the changes.

 


i am  going to use below URL for downgrade.

Howdy, Stranger!
