Hello,
Can anyone guide me through the steps for migration from oracle to postgres with config changes required, keeping in mind that neither I am a oracle DBA not postgres admin

Hi,
May I first suggest that you first look at some of EnterpriseDB’s technical literature. They have some documents which list what their products add to PostgreSQL to make it more like Oracle. If your firm isn’t doing this just to get out of licensing fees, they would probably be a good option for you. The basics of a migration is to look at the Oracle schema in order to determine which data types you’ll need to convert. Then, you’ll need to check which stored procedures you already have, and then what you’ll need to turn into PostgreSQL functions. Offhand, I’d say this isn’t difficult, but it may get very involved.

I second the ora2pg tool. Currently working on oracle to postgresql migration with it and ora2pg helps a lot.
But you can't get ready recipe for migration. There's ton of stuff to consider from trivial rewriting NVL queries to use COALESCE to more bigger stuff like lack of synonyms in postgresql. All depends on your current Oracle database.

You should read this through before starting the migration process.
