Do I still need to create a Back Up after using Migration Assistant?
I have a new 24 inch screen iMac. I have transferred (I think) everything from my old c 2015 21 inch iMac to the new machine using Apple's Migration Assistant. Do I still need to create a Back Up of my old data & files? (a subsidiary worry is that, if I do, I might overload iCloud with my old files and I will suddenly have to create a paying account for that)
iMac 24″, macOS 11.6
