Depends what you want to do and on aspects such as image sizes and the channel itself.
A channel will copy with ctrl-c. But to get it into a new channel. Make one, fill with white, edit -> paste.
Probably a more usual way is keep the channel with the original image as an xcf.

Then you can open the destination image Open As layers (but not the other way round)
Probably (certainty) there will be a mismatch in canvas size. Correct that. https://i.imgur.com/2BdxSvN.jpg (edit:correct shot)
Now put the channel to a selection for editing. https://i.imgur.com/N5hFwYY.jpg but you will find 99% of the time you need to do a bit of work with the selection for a fit.
Same procedure but send the channel to a layer mask: https://i.imgur.com/TmFba6T.jpg

Those examples were from luminosity masks, but if it is a simple selection, clean edges, no partial transparencies, instead of creating a channel consider selection -> to path. Then export the path to a svg file for later use.
