sed/awk script to replace only FIRST comment in the file

My first comment on every file contains the license message. I want to replace with a new license message. I used the below sed script, which replaces all comments. What is the modification or any other method with awk script for the below to edit only the first comment(license message)?

#sed -f sedscript filename

Try this - removes lines from 1 to first occurrence of */, then cats newcomment (assuming it contains /*...*/) and rest of file together:
sed '1,/\*\//d' oldfile|cat newcomment -

Might be a non- uuoc?
