You must perform this operation on the new instance of API Gateway. For a cluster setup, you must do this in one of the nodes.

After the design time data is migrated to new API Data Store, you must transform the data to be compatible with the new API Gateway instance. You can invoke the below REST API to transform the data.

Since transformation is a long operation, the REST API initiates the action and returns 201 Accepted status, if the invocation is successful. When the re-index operation is completed, API Gateway sends out a notification with the result details through registered webhooks. You can also invoke the following REST API to check for the current status of the operation.

A Success status message implies that quiesce mode for design time is completed.

If the transform API invocation for design time data fails with an error or the status returned with a failure, you must stop the execution of the next steps and disable the quiesce mode for design time in all the nodes and bring them back to normal state. You can clean the data and retry re-indexing of design time data. If the error persists contact Software AG support team for help with all the relevant logs for further analysis.
