Production impact when changing route-map with same content?

Planning on doing some route-map and prefix-list renaming. When testing i didn't see any impact when i just create new routing objects with the same content but different names.

When i then change them for example at router bgp route-map-in or out it shouldn't cause any interruptions, might have to do a execute router clear bgp ip x.x.x.x soft though.

Anyone with different experience?

It would still take the "new" route-map into the memory but would just override with the same content. It might trigger BGP message exchange with neighbors but since the same content, nothing should change. So probably almost no impact.

It's completely depending on what you change. Depending on that, your FGT or neighbors might lose routes then everything could stop working.

thanks, yeah i understand it depends on what i change.

but when i dont change anything, just replace route-map with one with another name but the same content. will that still have some effect, short interruption or such?
