General conversation. I'm of the view like Karlos that a slower transition is better in all circumstances, but there aren't many satisfactory studies to support/refute the idea and many people just seem to drop and raise calories overnight. My instinct and limited understanding tells me that calorie deprivation for a while sets the body up to store kcals as soon as energy intake increases dramatically, and that when reducing kcals suddenly the metabolism suddenly slows to 'starvation mode' to cling onto to energy stores and ditch metabolically expensive muscle protein. Making the transition more slowly would allow a more 'situation appropriate' metabolism in both cases.
I've always done slow changes either way, although never go on either extreme bulks or cuts with only modest calorie changes so am a bit lacking on practical understanding of cut/bulk diets. Just doesn't feel good to aggressively bulk/cut for me. I also have a fairly fast metabolism though and maybe that's why I never seem to have issues with bodyfat (highest I've every been is just under 14%)... might not be down to doing things gradually at all.
