So for classic Tasks list, you are able to manual sort and indent items. This sorting is persistent and not personal. List View sorting is set to None.

Manual Sort Buttons

Performing a migration using SP Migration Tool from SP2013 to SPO, classic task list functionality is still fully available.

  • Manual indent of items is migration
  • Manual sort order of items is NOT migrated (it defaults to sorting by list ID)

I have found a hidden 'Order' column which isn't visable anywhere other than opening another column settings on the list and changing the URL to &Field=Order

  • this Order column is not part of any content type or visible via SPD
  • this column is present in the migrated list, but it not populated with data from the source

Anyone know any more about this column, can I extract data somehow?

I currently cannot verify the migration part of the process but you can try to unhide the Order field and then start a new migration. The following PowerShell instructions allow you to unhide the Order field (remember to open SharePoint Management Shell with "Run as administrator" option).

$web = get-spweb http://win-c7to3h3n5cl/
$list = $web.Lists["WorkTasks"]
$field = $list.Fields.GetFieldByInternalName("Order")
$type = $field.GetType()
$mi = $type.GetMethod("SetFieldBoolValue",
    [System.Reflection.BindingFlags]$([System.Reflection.BindingFlags]::NonPublic -bor
$mi.Invoke($field, @("CanToggleHidden",$true))

I found the script here and here

  • thank you, I'll give it a try thanks
