Merging two branch with exactly same source

Hi Everybody,

I m trying to integrate Git on all ours existing projects. The problem is that we have different environment.

Then my idea was to integrate on the first branch the production environment and then on each environment create a new branch on each and then try to merge the new branch and the first branch (master) of the production one, to see each change made between the diferents environment.

In theory it’s very nice and almost very simple but when I do this on gitlab, the merge request appear to show me all the files even if the files are exactly the same.

Do you have a idea on how I can do this ?

Best Regards.
