Meta Business Suite Expert: Manual Asset Transfer from Restricted Portfolio

We are looking for a Meta Asset Specialist with proven experience in manual asset migration and restricted portfolio recovery. We have a high-value Instagram brand handle "trapped" inside a legacy Business Portfolio that has been hit with a permanent restriction. The Problem: The restriction on the portfolio has greyed out all standard "Partner" and "Transfer" tools. The Goal: We need to migrate the Instagram handle out of the restricted legacy portfolio and into a new, healthy, and Meta Verified Business Portfolio. Status: We have full administrative access to both portfolios and the associated Instagram account. The Instagram account itself is healthy (not community-banned); only the "container" portfolio is restricted permanently.
