My Client is looking to sell off one of their Business Units. This means all the users and their data from our existing production org needs to be moved to a new org to be bought for the moving out business unit. Now what is the easiest way to do this? I know we can migrate all users and related records but this is very tedious process. I am exploring if there is any way Salesforce can clone our Production org into a new Production org and then we can simply delete rest of the users and rest of the data i.e. anything other the Business unit. Is this possible?
