Changing the tariff on the RealHOST virtual hosting is free of charge. It is available only for existing services (the service status is “Active”). If the virtual hosting is in the “Stopped” status, then it must be renewed before changing the tariff.
You can change the tariff for shared hosting both upwards and downwards of the tariff plan.
Settings should be done in the hosting control panel https://realhost.pro/login
