Problem while Migrating user data from 10g to 11gR2

Question

Hi experts,
I am trying to Migrate users data(including password and security questions) from 10g to 11gR2 what approach i have followed is..
From 10g using API i retrieved users data including password and security questions and i stored all information into hashmap. This is one java program.
And then i am trying to create that user in 11gR2 using API which i retrieved from 10g . From this 11g program i am creating object of 10g and i am using that hash map to retrieve user information.But i am not getting connection to 10g , it is throwing exception like unknown application server.Both sides i used API only as it is recommended to use API instead of JDBC connection.
Help me in this regard ASAP and suggest if there is any other approach to Migrate users data.
Thanks in Advance

By using Trusted Recon, you won't be able to Fetch Password as it is.
Since your goal is to fetch passwords too, please follow another approach.
You won't be able to get connection to both 10g and 11g simultaneously in the same program.
So, break this task in 2 phases. First connect with 10g, fetch user data in CSV format and then connect with 11G and read this CSV to create users.
Once users are created properly, use APIs for creating challenge questions and answers.
I think, you are getting exception like unknown application server because you are trying to connect to both 10g and 11g environments simultaneously.
Follow the following steps:-
(1) By using 10G APIsyou can't obtain password of user profile in decrypted form. So, Fetch password by using tcDataProvider. It will give you plain text password.
(2) In a custom scheduler written in 10g, retrieve this data in CSV. After all you can't store this info in
String query = "SELECT USR_LOGIN, USR_PASSWORD, USR_FIRST_NAME, USR_LAST_NAME FROM USR";//Add all fields which you want to retrieve from your 10G
(3) Use this query, tcDataProvider, tcDataSet and Java I/O (or any other CSV Third Party tool like the ones obtained in csv.jar in XL_HOME/ext folder) fetch this info in a CSV.
(4) Once CSV is generated, 10g machine is no more needed. Connect with 11g using 11g APIs. Write your custom 11G scheduler in order to read this CSV and use 11g APIs and create users for each record.
(5) Once user records are created in 11g, the difficult part is done. Transfer the Security questions too by using this CSV technique.
