I have been googling and free online storage is too small (50 gig) , to do it in one go.
I was thinking though, can’t I just use the network cable that now goes into the modem, unplug if from the modem, then connect it to the other pc network connection.?
I have cable internet if that matters, with a cisco modem which only has one network connection.
Will I have to hook up a monitor to both pc ? And log in on both pc?
Newer pc had openSUSE leap 15.1, older pc has openSUSE leap 42.3
I wonder if its not easier to take the leap 42.3 hard disk from the old pc and temporary connect it through sata.
The new pc has enough sata and power connections to do so.
1GbE auto-detects wiring (it is part of standard). So two devices with 1GbE NICs can be connected using normal straight cable. I forgot when I used (or even saw) crossover cable last time.
