Is it possible to upload full Photos library from a diff computer (with faster internet connection)?
I have a very large Photos library (480GB)on my iMac (iMac #1) and would like to upload it to iCloud Photo Library.
However, to speed up the process I was thinking of copying the library to an external drive, taking it to another computer (iMac #2) (that has a much faster internet connection (business class) and upload it from there (creating a new user account on that iMac #2 and using personal iCloud login).
My question is - would this work? Using another computer (iMac #2) to upload all the photos, but then still have it connect with my iMac #1 (reading it as main library to synchronize from) and then synchronizing between other devices (iPhone, iPad, MPB)?
Hope I made sense.
