Hi, Your cannot change the license header without the owners permission and it’s ASF policy to not change any copyright notices without permission. Greg has given his permission via a software grant but there is still a large amount of 3rd party code in the repo.. Is some cases existing files do not comply with existing ASF policy and their original header will need to be added back. I would suggest you don’t do a bulk replacements and they will cause many issues. Please read [1]
Thanks, Justin 1. https://www.apache.org/legal/src-headers.html#3party
