With my new computer... I thought it would be a good idea to finally migrate from iPhoto to Photos... I had a iPhoto Lib of about 43 GB. When clicking on it, I was offered the option to migrate all pics to Photos, so I did. Its extension was subsequently changed into ".migratedphotolibrary". (same size - still 43GB) Yet... I see them nowhere in Photos. Is this normal? Can someone help/advise? Thanks!!
