[Pw_forum] Questions about ionic & cell relaxation.

Dear all pwscf users,
I want to do some ionic relaxations, but there's one question unclear:
Will the relaxation lower the original symmetry?
The reason why I ask this is that I want to optimize the cell and ionic
positions with some constraints, say, to keep the mirror symmetry along
z direction of the unit cell.
Any suggestion and comment are welcome. Thank you in advance.
