Transfer from Osirix MD 14.0 on Intel to Horos 4.0.1 on Silicon Tahoe

[Eberhard Lisse]

Hi, 

I am a retired ObGyn in Namibia and have 15 years worth of images on Osirix MD on an Intel iMac which I want to keep for liability purposes.

I want to decommission the Intel iMac and would therefor like to transfer the Osirix data, the folder of which is approximately 72 GB which is on the same WLAN as the M2 Mini.

How can I pull all images from Osirix to Horos most efficiently? 

greetings, el
