Selective Data Migration

bani · January 4, 2023, 7:16am

As per, “Tail-f ConfD Upgrade_Rev B_2021-04-19.pdf” document, CONFD supports data migration. And external intervention is required only when the data model is not backward compatible.
But is there an option available to selectively migrate some part of the data using external intervention (via a user provided upgrade client) even if the data model is backward compatible.

Looking forward to your response.

Thanks,
Bani

Hi,
You can do the same thing for both use-cases. Attach to the upgrade/init transaction and make the modifications to the new CDB (perhaps reading from the old CDB).
