Hi,
As Lustrous said, there are two mehtods, merge folder or create a collection.
Because one of your folders contains almost 10 times as many images as the other, I would say go with the merge folder:
In the Library module:
- Go to the folder that contains the 58 images and select all of them
- Drag them to the folder that contains the 457 images. You might need to scroll the folder list on the left panel to have it visible before dragging the images
- Go now to the folder that contains all the images
- In the menu select: View -> Sort -> Capture time
The images are now sorted by the capture time
To rename the images:
- With the images in the desired order, select all of them and go to the menu Library -> Rename Photos (or click F2). In the dialogue that appears you can customize the names to your liking as in the attached image.
Now the images are in the order you wanted, and the names are also in the order if you include a sequence number to them
If you're a suscriber, I recommend this tutorial
