Hi @Vijay Bhaskar Reddy Palle ,

For O11 Prem, which database are you referring to—the database mapped to the O11 environment or an external database?

There are some limitations when connecting O11 Prem directly with ODC. I would recommend reviewing the OutSystems documentation on Data Interoperability, especially the limitations section:

O11–ODC Data Interoperability – Limitations

You can also refer to the documentation on exposing O11 entities to ODC:

Expose O11 Entities to ODC

If the above approach doesn't meet your requirements, I'm not sure a direct database connection would be the best fit for your architecture.

One alternative would be to expose the required data through an API from O11 and consume that API from ODC. You could then gradually migrate the required data into ODC and let ODC work with its own data model.

This approach also keeps the O11 and ODC environments more loosely coupled and gives you better control over the migration strategy.

@Vijay Bhaskar Reddy Palle  :  The video you have referred is not for data migration but interoperability i.e exposing data from OS11 to ODC. This works irrespective of On Premise or OutSystems cloud as long as environments meet the required LifeTime and Platform Server version mentioned in https://success.outsystems.com/documentation/outsystems_developer_cloud/extending_o11_with_odc/interoperability_version_requirements/#data-interop

If you are looking for a true data migration please have a look at the current state of such initiative at https://success.outsystems.com/documentation/11/outsystems_11_to_odc_conversion/ and you can see the status as "The capabilities to migrate the data and end users of your O11 apps to ODC will be released at a future date."

Hope this answer your concern.
