First, COPY, don't move or "back-up" the designs. In fact copy all the data you want to save. Use an large thumb-drive USB to save all the data you want to keep. Then, when you transfer the data to the new computer, your data will be safe as it will be separate from either computer. When you transfer your data to the new computer, your design files will be set to open with Adobe. Your software may or may not work on your new computer. Check online for special instructions Before you begin. It isn't hard or scary as long as you have your data safe.
Thank you for your suggestions. Am still trying to get the embroidery platform that I have to transfer to the new computer. Makes me nervous as I have to delete it on the old computer before installing on the new.
