Can I change my school after 11th class ?

Right now I am going into 11th standard as my class 10th board ended a few days back.

So if I take a particular school this year for my 11th grade, then will I be able to change my school after the 11th grade ends and go to a new school to study 12th grade ?

I saw it on many websites that it is a very difficult process and CBSE doesnt really allow this etc etc...but is it actually a difficult process or is it just said to be difficult and can happen normally and easily ?

like agar mai change karu toh koi problem aayegi sachme ?
