We are researching upgrading to 10g(10.1) for database and Developer tools. The database is currently 8.0.6 and we use Oracle Forms 126.96.36.199.0; Oracle Reports 188.8.131.52.0; and precompile Pro*C/COBOL programs with the 184.108.40.206 environment. There appears to be quite a bit of information on the database upgrade. I am looking for Forms and Reports data as well as Pro*C and Pro*COBOL. The platform is currently AIX 4.3.3 ML11 and we will be upgrading to AIX 5.2.5 prior to the database upgrade. Would someone be able to point me to some reference materials? Are there any land mines I should be concerned with? Is this possible? Would going to 6i or 9i for Developer be an option if 10g is not?
