Copying a Model?

Hi, I was wondering if there has been progress on the front of being able to copy/deepcopy a model in JuMP?
Currently what I do is re-encode everything into the model but the encoding process is rather long and I would prefer to just copy the model.
I know that previously this didn’t work / wasn’t supported / created errors and so I am looking for a status update.

Although I will ask: why do you want to copy a model? Most times, you are better off modifying it in-place.

Oh excellent thanks! I presume it’s working then. (Because I know in the past it was technically present but did not do what was intended).
I am copying a model / constructing a new one because I am doing parallel processing – trying to solve a whole bunch of similar MILPs all at the same time. Same base model with a few different constraints.
