Architecture
Big bang migrations look efficient on paper. In practice, they concentrate risk and extend stabilization.
Big bang migrations promise speed. Move everything at once. Done.
In reality:
I have seen migrations planned for a single cut-over weekend extend into weeks of stabilization.
Not because teams were incapable, but because the approach left no margin for learning.
Phased migration works better:
It may appear slower at the start, but it reduces rework and shortens the overall timeline.
Migration success comes from control, not speed.
