Basically never use options like -i as they have lots of unfortunate side effects, like changing file ownerships and permissions besides destroying your original input if anything goes wrong. It's not worth it just to make a pretty one-liner.

Code:
awk 'NR==1 { sub(OLD, NEW); }; 1' OLD="xxyxx" NEW="XXYXX" inputfile > outputfile
# Uncomment these once you've tested awk does what you want.
# cat outputfile > inputfile
# rm -f outputfile
