I have 30 gigs of data to import to SharePoint online from a file system.
I have already tried mapping my Windows File Explorer to SharePoint. This process is very slow. It averages 10Kbs to 50Kbs.
I started following instructions here https://portal.office.com/EAdmin/Compliance/NewIngestionNetworkUploadJob.aspx?pwmcid=1&ReturnObjectType=1&workload=spo
to create a package then upload the package but I seem to be stuck on step 3 where you create the package something like
New-SPOMigrationPackage -SourceFilesPath -SourceFilesPath "E:\Source " -OutputPackagePath "c:\Save"
I will call MS for those errors. My question is if you have found a different way outside of web upload or syncing with one drive or as I pointed out mapping a drive with SharePoint.
