Transfer Photos Library to Monterey
I'm having trouble transferring my Photos library from an old MacBook Pro running Sierra 10.12.6 to a new 2021 Mac Book Pro M1 running Monterey 12.0.1
I have tried to follow the instructions on this help page but it's not working
https://support.apple.com/en-gb/HT209528
I have copied the old library to a USB drive and mounted the drive on the new MacBook. When I open Photos from the system photo library, go to File > Import and select the old library, I get a Cannot Import Item message. (See attached). If I follow the instructions to repair then the old library eventually opens in Photos but I have no way of importing it to the system library.
Can I simply move / rename the existing photoslibrary file in Pictures and copy the older photoslibrary into it ?
Any help or advice on how to complete this process would be much appreciated ! Thank you.
MacBook Pro (2020 and later)
