Shopify to Shopify SEO Migration

[Cris7]

Hello everybody.

I really appreciate your comments and advice.

I have two shopify accounts, each one with a web site, both sites are similar, products, etc.

Both sites has currently more than 3.000 visits per month, I want to redirect the domain #2 to domain #1 (traffic and site authority). Also keep just one account in shopify, maybe is possible to move the domain #2 into the other account store.

Do you know what is the best SEO step by step process to do that in order to not loss traffic and site authority?

Thank you very much
