A feature must be re-activated when it is upgraded to a newer version. If you are upgrading several SharePoint sites, you can save a lot of time by using a SharePoint power shell script to re-activate the feature. We have, however, become aware of an error which you may receive when re-activating Employee Training Management. The error message is as follows:
Exception calling "Add" with "1" argument(s): "A list, survey, discussion board , or document library with the specified title already exists in this Web site. Please choose another title."
Exception calling "Add" with "1" argument(s): "A list, survey, discussion board , or document library with the specified title already exists in this Web site. Please choose another title."
This error occurs when lists have been renamed and you try to re-activate the feature. It can, however, be fixed easily by entering a script into the SharePoint Management Shell.

} These scripts rename any lists with changed names and then update the feature. The lists are then changed back to their original names.
