Hello, I just ordered a Refurbed 21' iMac today. I currently have a mid 2007 MacBook running Lion that I have been backing up to an external HD via Time Machine (wirelessly). When I get the iMac... 1) Should I install the free Lion upgrade first? 2) Can I just set up the iMac directly from the MacBook backups? (When it asks if I want to transfer files from another Mac?) 3) Will I need to change the name of the Backup for future backups because I plan on wiping the MacBook and selling it? I would really just like a seamless switch from MacBook to iMac with all my same data, setup, etc.
