due to an update on the OS, please help to create a copy of the MVP permission rights (for easy portability)

When updating the OS, there is a problem with permissions (permissions need to be configured from scratch). But in order to set up new ones, it is necessary to somehow save the old ones from MVP, because it is not possible to view the old ones during the update. There is no tool to save it somewhere separate, I am asking Van Box management to help us, because it is a big problem for the update and because of it there are a lot of costs... The update itself is a complication, it is an expense. Please help at least save the existing permissions so that you can look there when new ones are installed! If you have not already done so that the permission rights are preserved, please help us somehow, please do not abandon us!
