Migrating from Oracle to PostgreSQL involves several steps, including exporting the data from Oracle, converting the data to a format that is compatible with PostgreSQL, and then importing the data into PostgreSQL. Here is an overview of the process:
-
Export the data from Oracle: Use the
expdp
utility to export the data from your Oracle database. This will create a dump file that contains the data in a format that can be imported into PostgreSQL. -
Convert the data to a format compatible with PostgreSQL: The dump file generated by
expdp
may contain Oracle-specific syntax that is not compatible with PostgreSQL. Use a tool such asorafce
to convert the data to a format that is compatible with PostgreSQL. -
Import the data into PostgreSQL: Use the
psql
utility to import the data into your PostgreSQL database.
Note that this is just a high-level overview of the process. Many details and considerations are involved in migrating from Oracle to PostgreSQL, so it’s essential to carefully plan and test the migration before executing it.
