Exclude File Type From Rename Script

Question

I need to exclude a single file type from the script below. Can someone show me what to add and exclusion for files that have a .partial extension?

#!/bin/bash
cd /data/user1/upload
thetime=`date +%Y-%m-%d_%H:%M:%S` #
for i in *.*
do
        extn=${i##*.} # save the extension of the file
                mv "$i" "${i%.*}"$(date "+_%Y-%m-%d_%H:%M:%S.${extn}")
done
mv *.* /test/user1

If you enable shopt -s extglob first, you can get all non-.partial files with !(*.partial).
