To duplicate an entire StoreFront click on the Duplicate StoreFront button on the General tab as shown below.
After you click the button a dialog will appear providing options on where to duplicate the StoreFront to.
You can duplicate the StoreFront to:
the account you are currently logged into
a linked account if you have any
a completely different account (credentials to a user with StoreFront permissions required)
After you initiate the duplication by clicking the Duplicate button, a job will be launched to perform the process. The duplication can take a few minutes, but will depend heavily on the size of the StoreFront being copied. The new storefront will have an automatically assigned domain name of <mid>-#.ultracartstore.com which <mid> represents the account’s merchant id and # is a sequence number.
