GVP for Aseptic Filling

Dear All ,

I am working in sterile biotech manufacturing facility and we have 2, 10 ,20 ,50 ml vial size for our product. Initially all the vials presentation qualified for tunnel validation , aseptic media fill validation ( 3 trails). During periodic revalidation we need to perform all vials presentation revalidation or we can opt bracketing approach if yes suggest me the possible brackets and references if any?
