I would like to approach the question slightly differently;
If you are moving to 'new' plant then look at it from all the supporting processes which are "relevant&needed&impact" for your product;
(risk assessment is the concept)
for eg., I would like to see your list in broadly two groups..
category 1 : procedure/method/process;
these are not going to affected unless new facility introduces/changes the attributes of any aspects of procedure/method/process
of below listed categories, ETO & sterilization are mandatory activities to be demonstrated; while you need to assess the what new variables (change in water for soap wash, etc., or introduction of new gowning material/procedure at new facility etc.,)
5.wash soap validation
6.Hand wash Validation
7.Gowning Wash Validation
12. Sterilization Validation
category 2 : equipment/facility
assuming that they are reinstalled; these ought to be qualified/validated as appropriate.
1.Building Equipment Validation
2.Water filter System Validation
3.Clean Room Validation
4.Air compresser System Validation
8.O3 Supplier Validation
9.Packaging Machine Validation
10.Production Validation (not quite sure what it is, if its process/product, even then it comes under category -2 )
I am not sure about medical devices, but reason/experience of pharma should hold good; i.e., anything which is ""dismantled/re-assembled - transferred/shifted"" equipment(even process) seldom behave well in the new environment;
the point is, it may not-be always adequate *to verify IQ nor is verification through OQ going to provide confidence.
hence an extreme/thumb-rule is ..., if it was required to be validated in current/existing facility then its required in new plant.
