Problem 1
===================================
a) If your database is Oracle and while running the migration script you get a message in the console like the one below:

create index icnt_eem_2 on tcnt_eem_entry_entry_map (
                           *
ERROR at line 1:
ORA-01031: insufficient privileges

b) If your database is DB2 and while running the migration script you get a message in the console like the one below:

SQL0551N  "USERNAME" does not have the privilege to perform operation "CREATE INDEX" on object "USERNAME.TWFL_WFE_WORKFLOW_EVENT".  SQLSTATE=42501

c) While running the migration script you get a message in the console which indicates that the database user does not have any privilege.


Solution 
--------

The database user does not have enough privilege to create an index in the database. You should grant "create index" privilege to the database user and then re-run the migration script.



Problem 2
===================================

If your database is Oracle and while running the migration script you get a message in the console like the one below:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 Migration Failed :  ACG

 Please see the file for further details :  /home/wpcuser/wpc532/logs/errfile.log
 
And in the errfile.log file you see this exception:

java.lang.NullPointerException

        ....
        
Solution
--------

The exception is caused because you are using an Oracle jdbc driver 10.2.0.2 or higher on your Oracle client to connect to the Oracle server. 

Downgrade your Oracle JDBC driver to 10.2.0.1. Set your current instance to connect to the original backed-up database and run the migration script.
