The following items are not copied from production to Release Preview accounts:
Websites and web store domains
Domains are not copied from your production account to your Release Preview account. If you would like to test your websites or web store, you must set up domains in the Release Preview. For more information, see Manual Certificates and Set Up Domains for Web Stores.
Customer Center roles
Customer Center roles are not copied from your production account to your Release Preview account. Due to this limitation, customer login functionality does not work in Release Preview, even if it has been working in the production account. If you want to set up this functionality to work in Release Preview, you can do a CSV import of customer records into the Release Preview account. Then you can set passwords and check the Give Access box for customer users.
