Thanks @BrandonBerner for your answer.
I asked this because I had a bad experience with adding accounts from my local IP to a new proxy. My local IP is from Europe, but the proxy is from USA. Facebook can easily detect this and will ask for an ID verification.
I thought there is a workaround for this, by assigning my local IP address to the Massplanner on the VPS server for the accounts that are currently running on my local IP.
If I understood right, you are saying that if I want to migrate the Massplanner on a VPS, the only option I have is buying new proxies for every account I currently run on my local IP.
