Preserving old Created On dates during SharePOint Online migration

We are currently migrating files from our on-premise fileshare to SharePoint Online. We wish to carry as much file meta data from the fileshare into SharePoint Online, but when we drag&drop a file from the fileshare to our Documents library in in SharePoint we lose the original Created On data stored on the fileshare i.e. SharePoint site column 'Created' is populated with the date the file is created on SharePoint and not the original date of the file.

Could anyone advise on how we can carry the Created On date from the fileshare into SharePoint?
