Whatever reason for the move back to http from https - if the move is to be permanent, I'd be using the google change of address tool: [support.google.com...] + this page includes other guidelines for you to follow
... Use the Change of address tool when your site move entails a domain or subdomain change, such as changing from [fish.example-petstore.com...] to http://example.com or [example-petstore.com....]
Note: The tool does not currently support the following kinds of site moves: subdomain name changes, protocol changes (from HTTP to HTTPS), or path-only changes.
