Accidentally the version history of the list item has been deleted.
Is there a way to restore the deleted version history of the list item ???
My recommendation is to export version history in bulk periodically and keep the results for either analysis or data recovery…We just launched an Online tool to export SharePoint Version History in bulk. You can select the fields from a list, the results of which are sent to your inbox in Excel format. You can rerun these jobs which are saved in One Tap! Check it out here: http://sharepointversionhistory.com and let me know what you think.
