Unsupported List Templates RRS feed

  • Question

  • We have a large farm with approx 2,000 site collections that we want to migrate.

    Some of the sites have used custom list templates - and for those we are seeing the message "The list template ##### is not supported"

    What approach can be taken to migrate lists with unsupported list templates?

  • I ended up developing a custom solution to solve this issue.  It involved:

    * Enumerating SPMT logs using C# and writing to Seq using Serilog

    * Using the Seq UI to report on template not supported messages

    * Custom PS script to 'clone' unsupported lists to generic lists

  • Hi DNeimke,

    Can you please share the Power Shell (with just 1-2 sample columns) to clone unsupported list (on OnPrem environment) to generic list (on SharePoint Online) ?

    Thanks
