Comment puis-je déplacer des messages vers un nouveau message ?

[JammyDodger]

Having a little root around, I think this is some relevant information:

Back-end allows moderators to use merge/move posts to private message, but front-end does not

The decision to not show “move to new PM” option for moderators was made explicitly in: https://github.com/discourse/discourse/commit/dc2776bcddc07e69e5a4ab92526f6238f3a5ccd7 This is because the moderators do not have permission to see PMs and the relevant code will fail at: https://github.com/discourse/discourse/blob/310952fd6a2fb74127175486bb0d6723640a274d/app/models/post_mover.rb#L66

Looks like it may be possible to make a change, though I don’t think the issue has cropped up enough to make it a priority.
