Photos converted my iphoto files but failed the first time so now I have 2 Photos libraries. One library is larger than the other but it is not the default library. Is there a way to consolidate or delete one of the Photos libraries with losing any photos.

You can switch between Photos Libraries by double clicking the library you want to open.
To merge the libraries, open the smaller library and export all photos to folders on the Desktop with "File > Export > Export Original...". Then import the exported photos into the larger library. Photos will detect duplicates on import and you can skip them, if you exported the original versions. Make the library you are importing to your System Photo Library by enabling the Photos > Preferences > Use as System Photo Library.
After you imported the photos from the smaller library into the larger library you can delete the smaller library.
i now have 2 photos libraries how do I consolidate them
