Tip for Disabling all current Control Budgets, and create new control budget cover all COA segments

Hi All,
Hope you are doing well.

Please find below the current Budgetary Control setup and the proposed new requirement. We would appreciate your inputs on the recommended approach and any best practices for handling this type of change.

Current Setup

1. We have a 9-segment Chart of Accounts (COA).
2. There are currently five Control Budgets enabled, with each Control Budget covering only three segments. All five Control Budgets are already In Use.
3. Some of the nine COA segments are not represented in all five existing Control Budgets.
4. The Budget Calendar is yearly (Budget-25, Budget-26, etc.), while the Accounting Calendar is monthly.
