Replacing Oracle with Postgres

  • 1.  Replacing Oracle with Postgres

    Posted 8 days ago

    Hi Folks

     

    We are planning on moving to 12.3 early next year and have spotted that 12.3 supports Postgres as the underlying database.

     

    Has anyone migrated from Oracle to Postgres and if so did you encounter any issues ?

     

    Regards

    Joe

    I can just give you some approaches on migrating from oracle to postgresql:

    1) Use Unload in oracle / and Load in posgresql to migrate
    This can take quite some time and memory (on the utilities)
    Not recommended to unload / load with all statistics/execution data for that reason but only for definitions. Make sure you only export the last month of statistics by reorg/unload/... before starting the migration or only migrate definitions and skip all statistics records.

    2) Setup a new system with postgresql and use transportcase or client copy to move project by project to this new system.

    Hope that helps.

    Thanks Tobias

     

    I was hoping it was that straight forward.

    We never brought the stats and reports with us when we migrated to a new oracle database , so these are  no loss.

     

    Have you  encountered any issues with characters sets ?
