Migrating files from SharePoint to Box keeping the file/folder date intact

I am a Box & O365 Admin. I’m trying to migrate data from SharePoint to Box and I would like to preserve the file/folder creation/modify date stamp. I have tried dragging and dropping from the Mac finder, I’ve tried using Box Shuttle and I’ve tried using an FTP client. None of those options allow me to preserve the date, they all migrate with the date/time of upload. I did some researching and found information on CloudFastPath (by Box Shuttle), it says it’s Box’s recommended tool for enterprise migrations. When I go to that page the site times out as if it may be a dead link. Can you tell me CloudFastPath is still available and if it’s still recommended by Box? Or does anyone have another way I could accomplish preserving file/folder dates while migrating?
