Can I change my VPS account to other broker account?

It may takes some time.
Anyway, you can check it on this page:

As long as it meets the requirements, you can apply for a VPS monitoring account to be restored to a trading account other than your initial VPS monitoring account. This account, however, must be in the same personal area.
Yes, you can, but it also depends on your broker, because my broker FP Markets does allow it, but I'm not sure what broker you are using.
