What kind of PERC is it, specifically? I cannot speak for the PERC3/DC and it's variants (the kind that are work under the amr driver). However, for the PERC3/Si and Di, doing what you describe is allowable. After you move the disks, the controller will probe the disks and recognize the arrays, then ask you if you want to accept the configuration that it's found. After that, it should Just Work.
