SharePoint Migration Tool - PACK FAILURE","Packaging Failure:Unauthorized access to source file
Few Minutes ago i stumbled upon a widget in the new MS 365 Sec & Compliance Center (partly in Preview now). To try this out, pls. check your Exchange online Role for "Mailimport/export".
This tool seems to handle Migration of WHOLE file share data drives and other file issues, when the original metadata are corrupted. I think now, that your migration issues are originally a redundant or inconsistent metadata problem. Mostly the failured migrations deal with inconstistent version history of files and in doubt the AI must decide whether it lets your data in or not and because of that error you ´ll get empty metadata on "Created" or "Modified", even no files at all. The standard in SharePoint is that on Uploading a file SharePoint writes only the uploaded Date, not the originally created Date. So in good case your uploaded files get the "Created" Date as the Upload Date. Precondition is always, that you are the owner of that document / file to upload a file. And your Users have to have a unique account, establishedin the Azure Active Directory of your O365 Tenant.
I didn´t test it yet, but you can answer here if it works.
And I found more Infos in this link: https://docs.microsoft.com/en-us/microsoft-365/compliance/importing-pst-files-to-office-365?view=o365-worldwide
There is a new way to import "old" files via PST into O365. Hope that helps additionally. Yours, Eva.
