This approach allows you to buffer the "template" file without batching the whole thing into a byte[], perhaps allowing it to be less resource intensive.

var templatePath = @"c:\data\hello.docx";
var documentPath = @"c:\data\newFilename.docx";

using (var template = File.OpenRead(templatePath))
using (var documentStream = File.Open(documentPath, FileMode.OpenOrCreate))
{
    template.CopyTo(documentStream);

    using (var document = WordprocessingDocument.Open(documentStream, true))
    {
        //do your work here

        document.MainDocumentPart.Document.Save();
    }
}
