So I’m contemplating replacing my trusty 2013 13" MBP with a new 14" MBP once Apple launches it in the hopefully not too distant future. Two issues I’d be curious to hear opinions on.
1) Continue to use old TM backups or start new TM backups? There are simple instructions to continue using old TM backups with a new Mac (it’s an old link but I’ve confirmed the method still works). The advantage is added convenience because I don’t need a new disk (old TM disk too small to comfortably hold separate old and new TM backups), which means I don’t need to swap disks when I want to fetch an old copy of a file. The cost of the new disk is not really an issue, the convenience is. Is there any real negative to just fudging the old TM backup to continue accepting backups from the new Mac?
2) Which is the best interface to migrate over from old Mac (USB3 & TB2) to new Mac (TB3 only)? I have a TB2 Gigabit adapter and I wasn’t necessarily planning on buying a TB3/USB-C Gigabit adapter because I also already have a TB3/TB2 adapter so I could use the old Gigabit adapter with the new Mac in the very rare instances I need to do that. But if I now need to use Gigabit to connect these two Macs as the fastest transfer method I’d just get a second Gigabit adapter. Any better/faster options for migration than Gigabit?
