This is during an upgrade from Odoo 14 to 16.

I have a duplicate view in Odoo for the web.frontend_layout

One marked with the External ID 'web.frontend_layout' is the correct upgraded version.

Another is unmarked with the External ID, and is a stale outdated version.

If I try and delete the stale version.  I get an error: 

The operation cannot be completed: another model requires the record being deleted. If possible, archive it instead.

Model: View (ir.ui.view)
Constraint: ir_ui_view_inherit_id_fkey

If I try and archive it, my site breaks.  How do I get rid of this duplicate view and allow the updated view to take hold?

Thank you,

Anthony Taylor
