Idea Summary
In Oracle APEX, when changing a region type between similar report components—such as Interactive Grid (IG), Interactive Report (IR), and Classic Report—the platform currently requires developers to recreate the entire region from scratch. This process results in the loss of shared attributes like column headings, alignments, format masks, and other display settings.

The proposed idea is to preserve common report attributes during region type transitions. If the new region type is functionally similar to the original, APEX should intelligently retain and migrate shared configuration settings to reduce repetitive work and minimize human error.

Use Case
This enhancement would be especially useful in the following scenarios:
* UI Refactoring: When developers need to switch region types to meet new UX requirements or performance goals.
* Prototype Iteration: During rapid prototyping, where region types are frequently changed to test different report behaviors.
* Maintenance & Upgrades: When updating legacy applications to newer standards or features, such as moving from Classic Reports to IR or IG.
Ultimately, this would save time, reduce errors, and improve developer productivity across the board.
 

Preferred Solution (Optional)
Implement a region-type-aware migration engine within the APEX builder that:
* Detects when a region type is being changed to a similar report type.
* Automatically maps and retains shared attributes (e.g., column headings, formatting, alignment, visibility).

This could be integrated into the region editing interface or offered as a guided wizard during region type changes.
