Hello Experts.

Current Scenario of my working environment is as :

IBM RS6000 servers
AIX 4 OS
Oracle 7.3.3
SQL Forms 3.0

There are almost 500 forms ,1000+ reports and 50 Pro*C programs
and now we need to migrate our database to 11.1 , forms and reports to new servers

I am totally new to migration and upgradation,so can someone please let me know the the exact way to upgrade ?
