swapping horses in midstream

Changing course dangerously

Swapping horses in midstream means changing plans, leaders, or methods in the middle of a difficult undertaking—when such a change is risky or inadvisable.

The image is of a rider dismounting one horse to mount another while crossing a river, an obviously perilous maneuver.

Often used in political contexts: You don't swap horses in midstream during a war.

The phrase typically argues against change, though it can also justify a necessary switch despite the risks.
