Hello- In the very near future I will be upgrading from a 2007 iMac to a 27" 5k. I currently back my computer up to a Synology 213+ dual drive via Time machine, and also a separate external drive just for my photos via CCC. I'm a bit nervous about the upgrade, as I am not sure how to get all of my data properly copied from the RAId drive to then new iMac. If its something I should do at an apple store, fine. If its something can correctly do in place that would be fine too although I haven't done this before. Any help or suggestions welcome. Thank you.
