Restoring photoslibrary from a data recovery disk after computer crash

I recently experienced a complete hard drive failure in my iMac and at the same time my Time Machine backup was also lost! Thankfully a data recovery company was able to recover my data and I have a large "Photos Library.photoslibrary" file that I would like to restore to my new computer. Is it simply a matter of dragging that file from the external drive that holds the recovered data into my Pictures folder or is there more to it than that?

Thank you.
