Old store url to redirect to new store while keeping old store shopify accounts and data available

[L2L]

Hi community!

Store A is owned and operated by mister Smith under its domain www.mistersmithstore.com

Mister Smith will soon stop his activities and wants his clients to be redirected automatically to Miss Doe Store when they enter www.mistersmithstore.com

Miss Doe has opened her own store B will operate the company under a new name www.missdoestore.com

Mister Smith wants to keep his shopify account with past sales/customers datas  available for him for few more months, but do not want his store (A) to be public, and want all people typing his store url to be automatically redirected to Miss Doe store (B)

what should be done ?
