This is a good question.
Technically the process is same with out changing any process controls.
But at the same time you have changed the Material of Construction of a Primary packing material where sterile material is held for a long time stable with out hindering the quality properties of the filled product.
You have a major change control in terms of the Primary packing material and may be your supplier.

You need to perform a Media fill with out any doubt.
Any regulator will question this when he review your Batch Manufacturing records and also your Primary packing material storage records.
