Possible to only migrate files from SP07 to SPO that are newer than 7 years?

Hello, we are a content matrix customer on the latest version, we are currently migrating a few thousand sites from SP07 MOSS to Sharepoint Online, we are now processing some sites that have amalgamated a lot of data, one being over 500GB but there is around 100GB of data that is older than 7 years which will allow us to stay within our allocated spend if I can migrate the site without migrating data over X years old.

Is this possible with powershell or the ui?  I haven't managed to find anything on it and would have thought this was possible.

Thankyou,
