Import iPhoto library to Photos
I've been watching the improvements coming to the Photos app for several months and I am ready to take the plunge to switch my iPhoto library of 30k plus pictures to Photos. I do not use any cloud based storage; I have my iPhoto library on my local drive, backed up to an external connected hard drive through time machine, as well as a complete copy to another external hard drive. I have spent much time tagging faces; which is the most important to me and I want to make sure they transfer. What is the best way to bring all the metadata from my current iPhoto library to the new Photos library?
I know I'm asking a rather basic question, but I'm being overly cautious with this. Thanks for any help you can provide.
