We currently have an install of Enterprise Edition that is in evaluation mode while we evaluate some software that uses it as a back end. Since we normally have only Standard Edition installs, we don't have any Enterprise licenses. The software requires Enterprise, but by the looks of the timeframe, our trial license will expire before the evaluation period is completed. Obviously we don't want to spend the $25,000 for an enterprise license that we might not end up using, so I was wondering if it is possible, even via contact with Microsoft, to somehow extend that 180 days.
