Moving photo library on external drive to a new Mac Mini
I have around 0.5Gb of photos on my iMac in my photo library that's held on an external drive and synced to iCloud to hold original resolution photos. I recently got a Mac Mini M2 and would like to use this as my main computer in future as its much faster. Can I simply move the external drive to the Mac Mini and identify this as the library without a lot of re-syncing or uploading - it took almost 4 days to upload my library to iCloud and I don't want to repeat that! The library is of course already synced through iCloud so shows up on my Mac Mini, but I'd like to have the EHD connected to it.
