New to PowerShell and SharePoint, i have a WebPart that contains a SharePoint List.
After adding and installing the solution and enabling the feature, i added too many records to the list. Now i added another column to the list and i want to update the feature without loosing the records inserted before... I have been told to desactivate the feature, then, install an updated version of the solution and activate it again... But in this case, i will loose all the records i added previously.
Can anyone help me please?
