1Tb drive are so cheap now, better safe than sorry to have an extra backup just in case. I would also manually copy the library to a second external drive just for safe keeping.

Since you are on Sierra still I think you will be fine, I suggest you back up the photos library over time machine. It is new and I hear there are lots of migration bugs so I am holding off.

What I will say is, I wouldn't upgrade to High Serra right now. Initially upgrading the library took a LOOONG time and syncing all those photos to iCloud when I changed the external to be my system library took days, but I have had no problems since.

My phone and iPad are iOS11 and I have had no problems there either (even though I have not upgraded my photos library to the High Sierra version yet.) I keep all of my photos on an external 2Tb SSD over usb3 for speed (too big for my macbook pro 1Tb internal SSD. I sync all photos in icloud and on my phone and my ipad and multiple AppleTV's and have no problems. It is much faster than iphoto and since launch has brought become comparable to iphoto in terms of features and with 3rd party integrations actually surpassed it. As for the rest of it, keywords etc seemed to migrate over no problem. I can't tell you how many faces it was, but photos does such a better job of identifying faces, most of them were back in no time. I probably upgraded too soon (back in the day) and lost some of my face data that I had to reconstruct, but those wer faces I had manually added or I think already had some problems. I currently use photos and am having no problems. I have a library that is over 100,000 pics and 1.1 Tb.

If Photos is not the answer, what consumer-based digital photography solution is available for Mac, Android-based smartphone (running Android 6), and iPad Mini (running iOS 11) can be used to reliably organize and manage a library of this size?

Will I be forced to migrate to Photos? If so, will all that valuable metadata (possibly thousands of photos) be lost? Is there any way to avoid this? (I bought my first digital camera in November 2001.) I have roughly 65,000 images in my iPhoto library, dating back to before the beginning of the first version of iPhoto. I am deeply concerned that migrating from iPhoto to Photos will ruin all that metadata and organization permanently. I store this information, and more, for family members, volunteering for local civic organizations, events planning, and work projects. I also have alot of newspaper-style prose captions stored as metadata in the Comments pane for quite a few photos. I have a lot of time and effort invested in organizing Events with titles that I wrote like highly abbreviated summaries. This is tremendously disappointing, as Apple's new official Photos app seems to be more like iPhoto Lite, or iPhoto 2004. I am aware that iPhoto is EOL'd, meaning Apple no longer supports it. Now on Sierra, and so far, iPhoto is still working.

Both machines use the same iPhoto library (library stored on an external portable hard drive), plugged into either computer (one at a time) via USB cable. I upgraded both machines to MacOS 10.12 Sierra recently. My other family members use iPhoto 9.6.1 on a MacBook Pro. I have iPhoto 9.6.1 installed on my iMac. My family has an interesting arrangement. Apple's concept of a well-designed "digital shoebox" has proven itself invaluable, time and time again. I rely heavily on iPhoto's proprietary features, and have been since I started using the first version of iPhoto when Apple released it well over a decade ago. I have an iPhoto library that contains about 65,000 images.
