You will need to delete the existing flash image before copying the new image across. Or on some switches/configurations you are prompted to erase the flash first as part of the tftp copy process.

Be careful if erasing the existing image that the new image is successfully copied and not corrupted before reloading the switch to prevent problems with booting the switch.

You need to verify the requirements of the new IOS image you are uploading. If you have an image that is 12 MB large and the router you are upgrading only has 8 MB total, then you will need to get more memory for the router.

archive download-sw /overwrite tftp://address/IOS name

Just make sure you copy your existing flash to tftp before trying to upgrade. That way, you'll have a back-up.
