Migrate a Library a second time

FiC5020 96 Reputation points


I want to migrate oure Sharepoint Foundation 2010 Libraries to Sharepoint Online. Works fine so far.
But for testing I migrate a Library in Summer to Our Sharepoint Online Tenant in the now Productive Sharepoint Site.
After Success I delete it because its only a Test.

Problem is now. I could Migrate every Library, but only this one the Documents (PDF, Docx,...)
Errormessage in Logs: Error or timeout for server processing of the file.:Not all element in the package were migrated.

I test it in another Testtenant oder Sharepoint. It works, but only on time. When i try it a second time, I get a empty new library in case I delete it before,
or the documents would not be updatet.

Error: Error or timeout for server processing of the file: Not all elements in the package were migrated. (Attachment full message)

Question: Is there in Sharepoint Online any Documentation of Migrations in the past, or could I reset past migration Infos?

Does anyone have experience with this ?

    Yes, you have understood correctly.

    Thank you for your suggestions, which unfortunately I had already tried. I also waited over the weekend after deleting the bins. Just wait for replication / latency times.

    Unfortunately, the problem has not been solved.

    My solution was to use the trial version of https://saketa.com/migrator/. It worked perfectly, even several times.

    Thanks for your help.

    Based on your description, I understand that you migrated a document library from SharePoint Foundation 2010 to SharePoint Online, then you deleted the migrated document library in the SharePoint Online. After that, when you start a new migration to move all contents in a site collection, the document library that has been migrated cannot be moved at this time.

    1.Please try to delete the migrated document library in the two stage recycle bin of SharePoint Online.
    2.Start a new migration to move the issued document library.

    You could go to saved migration sessions to reset previous migrations.
