About to buy a 27 inch 2017 Imac and want to move my Imac 2009 content into new Imac from my snow leopard 2009 Imac. Going to use the Migration application present on both computers. Can I use a regular CAT-7 ethernet cable to connect both computers to each other since the 2009 Imac has an older ethernet port than the2017 gigabit ethernet port in 2017 Imac. What Im trying to accomplish is to put everything from my old computer onto my new computer as easily and efficiently as possible. My 2009 content is in old snow leopard and old itunes accounts that exist on 2009 Imac. Will it easily go into the newer operating system and itunes account on 2017 Imac with no glitches? Thanks
