Rebranding and Redirecting from One Shopify Store to Another

[MattG01]

We just finished a rebranding for our company.   As part of that rebranding we moved from one domain to another.   (BrilliantGifts.com to ShadowBreeze.com)   Brilliant Gifts and Shadow Breeze are two different stores both on Shopify.    We used the URL Redirect tool on the Brilliant Gifts store to redirect each page on the site to the matching page on ShadowBreeze.com.   To redirect the home page on Brilliant Gifts we used redirect from /root to https://www.shadowbreeze.com.   All of the redirects seem to be working just like they should.

I would like to use Google's Change of Address tool in Search Console to officially let them know.   Both BrilliantGifts.com and ShadowBreeze.com are verified properties on the same Search Console account.    However when I try to submit the request I get the attached error:

Shopify does not allow me to redirect https://brilliantgifts.com or http://brilliantgift.com using the redirect tool.  When I try I get the following:

Any suggestions on what I need to do to get the change of address tool on search console to work?   I plan to keep the brilliantgifts.com store open for a year to be able to access past orders, etc.      Any help would be appreciated.
