Hi @echoi2 ,
Welcome and thank you for asking on the Instructure Community!
I recommend exporting your canvas course shell to your computer files by going to your course settings and clicking on export course content. Then, in your new course, click import existing content, and select that file that was exported from your original course. I will provide an image below as a reference!

If your current school has Canvas Commons enabled, you can also share your course to Commons publicly, and access it on your new account and import it from there, too. https://community.canvaslms.com/t5/Canvas-Commons/How-do-I-share-a-resource-to-Commons/ta-p/1798
I hope this helps you! Reach out with any additional questions or concerns, thanks!
