Google Search Console Has New Tools to Help With Site Moves

Google is rolling out new features for Search Console’s change of address tool to further assist users with changing domains. The change of address tool within Search Console allows site owners to notify Google when a website has moved from one domain to another. It can also be used when moving a site from one subdomain to another.
When Google is notified about a domain change it will begin to prioritize crawling and indexing the new domain over the old domain. Submitting a change of address request will also tell Google to forward signals from the old domain to the new domain.
