Hello, 

It is IPS's own cloud service which I could move my forum, because the current provider is really a lot of problems with this platform to platform, but a my blog works well for what it is made of WordPress. I have purchased a forum for self-hosted payment is not In The Cloud

Thank you!

You would be best to simply open a ticket in the Client Area to discuss this with sales as you have a 'self hosted' licence.

I'm 99% sure you won't be able to install WP on a Cloud account though, but you could possibly use Pages and / or Blog to duplicate what you have ?

Best to speak to sales regarding the self hosted vs cloud question though, they will be able to advise you on a suitable course of action.
