In Oracle Fusion, what is the impact of Renaming Business Unit on Cash Management?

Summary:
We are currently implementing Oracle Fusion for one of our clients. The implementation includes multiple Legal Entities, with one Business Unit (BU) per Legal Entity.

The client is planning to rename their business unit. However, they have already used the business unit in their transactions/operations.

Example:
Old BU Name                                       New BU Name
GMMA_METRO_EAST_1_BU                GMMA_3_METRO_EAST_1_BU
GMMA_METRO_EAST_2_BU               GMMA_3_METRO_EAST_2_BU

We would like to ask for confirmation if the following items will be impacted in the BU name change. If Yes, how will each be impacted?
