Purchase Order Archiving & Purging question

We are currently working on a Purging and Archiving project where the goal is to archive and purge old Standard Purchase Orders for which the complete P2P cycle is Completed, the PO is closed, the invoice is closed, payment is completed, and accounting is transferred to GL.

However, these standard POs are linked to Blanket Purchase Orders that are still open in our Oracle EBS R12.2.9 instance.

Now the question is:

Can we archive and purge such standard purchase orders even though their parent blanket purchase orders remain open, given that the full P2P lifecycle for the standard PO is complete?
