how to restore Logic Pro projects on new Mac from backup

My iMac died. I have a new MacBook Pro. I installed Logic Pro and all my sound libraries on my laptop (fresh install). I have a Time Machine backup of my dead iMac. I have retrieved all of the files I could think of off that backup drive and saved them to an external SSD. One thing I grabbed was my main Music folder and it's saved on the SSD. I haven't moved anything onto the internal hard drive since I'm wanting to save things externally. My sound library is now also on the external drive SSD instead of internal (which is a change I'm making with the new laptop).

Logic works. I could create a new project and run with it. But I wanted to make sure my old tracks work before I did. I was also trying to find my template so I could use it. And I discovered the logic projects I have saved do not open. Is it because they need to be in the right place in my internal hard drive and not on the SSD? Am I supposed to use Save As to move projects to an external hard drive?

Are there additional files (system files, preferences, settings) in different folders in my backup that I need to retrieve/restore before my old projects will run on this machine?

I'm worried I may have lost all my work. Please help.
