Hi Yasuyuki,
The plan looks good. it can be improved. it might work well with small environments hosting <100 bots if your production environment has more bots i would recommend you to introduce a layer 4 load balancer In front of the Application servers. also consider the system requirements for version 7 there is changes is supported OS in version 7 if your current environment is configured in windows 10 you can work smoothly with this plan else you might face some difficulties testing your process across the old and new versions
