Hi @jennifer_mcvay -
There are a couple of different ways you could do this! You could export your content from your old course and import it to your new one (https://community.canvaslms.com/docs/DOC-12935-415257077?sr=search&searchId=18a21ae4-7feb-471a-94db-...) Or, if your institution supports it, you could use Canvas Commons. (https://community.canvaslms.com/docs/DOC-11177-38287725291?sr=search&searchId=8c09117d-ba2d-4d0c-bcb...)
I hope this is helpful! Good luck!
