Based on my understanding the upgrade will be perform by the local operation team who is NTR Certified in Thailand. If you have any further queries regarding the operation task, appreciate you bring this up to your respective manager. Please do advise the rundown plan with the site detail including the site setup and we will register this project/change with NICE IHD. The VR team will review and advise accordingly after receiving the breakdown. Please advise closure in regards to this case.
