You can try use bash script, for example

#!/bin/bash
docker login -u -p https://harbor.domaine.com/
for image_name in $(docker images --format="{{.Repository}}:{{.Tag}}" | grep nexus.domaine.com)
do
  new_image_name=$(echo $image_name | sed 's/nexus.domaine.com/harbor.domaine.com\/project_name/')
  docker tag $image_name $new_image_name
  docker push $new_image_name
done
