I am in the process of upgrading my Mac Pro from Snow Leopard to Mavericks. I will do this by performing a clean install on a new drive and then manually moving over all important data (documents, pictures, iTunes data, Mail data, certain preferences and application support files, etc.). What I am wondering is whether I should set up the admin user account (I only use one account) on the new Mavericks system with the exact same name and password as on the old system. The idea behind this is that A: I won't get confused and B: This might prevent permission issues when copying over data from the old system, since both users are identical (sort of). But maybe I am wrong and this will actually create potential for trouble. What is the consensus on this?
