Most sites are on hosting chosen years ago for reasons nobody remembers.
Move My SiteMigrations go wrong when somebody flips DNS and hopes. We stand the new environment up, test it properly, and cut over when it is genuinely ready.
Matched to your actual traffic and stack, not the biggest plan.
Tested on the new host before anything points at it.
The parts that usually break in a move, handled deliberately.
Set up and renewing automatically.
Measured before and after, so the move is justified by numbers.
What you are paying versus what you need.
