Why? (Beyond the fact that all migrations are discrete events and therefore unique)
Assuming this is a serious question?
The language and culture shock of moving between Germany and German Speaking Switzerland, or between NI and the Republic is going to be pretty much zero. Some local laws might be different and that is pretty much it.
A family moving from Spain to Switzerland is going to experience moderate culture shock and considerable language shock.
And a family moving from North Africa or the Middle East to Ireland (or Switzerland, or France, or Germany, or the UK) is going experience very considerable culture shock. Lets be honest, they will. All sorts of things, from the predominant religion, to standards of dress, to attitudes towards gay people and the status of women will be very different. All of that on top of any language barrier.
That is why I was interested to know where Switzerland's immigrants came from
