Do I need to install the CMS platform I want to migrate to?
Not necessarily, you can try Demo migration with CMS2CMS even if your Target CMS (the one you’d like to move to) isn’t yet installed. In this case, a limited amount of your website data will be migrated to one of our test sites, and you’ll get admin access details to view the results on both front- and backend.
However, in order to complete your Full migration, you are going to need the Target CMS installed.
