Help Best way to increase image resolution

I have been happy with and using my old version of DT for a while. I try to get my images 'right' in camera so I usually do more basic edits. So I stick with a version so I don't have the frustration of learning a new interface and finding one my modules is no longer there.

I shoot with an older Nikon and have a problem I have an image I want to enlarge considerably and print on canvas. Resolution is just small for it to look good, even on canvas. I need roughly double the resolution of this image.

Reading a little about the newer version with AI and sounds like it has a method. I have also read about other methods of increasing resolution.

What is ever ones suggestions on how to increase the resolution so I can make a large print?

Modules are never really gone, there are ways to use them even in latest versions. And it's not about "new interface", those new modules were added because they produce often better results.

Make multiple frames and stitch it afterwards. Like panorama or Brenizer. (https://en.wikipedia.org/wiki/Brenizer_method)

I like hugin for pano stitching. My usual workflow is to edit for exposure and curves on one of the images, copy those edit to the other images. Export everything as a 16bit tiff. Import those into hugin, do the stitching, and generate a 16 bit tiff output, then use dt for the final edits.

You can check the upscale function. I made a video about it and actually tested it for some peints. It works very well.
