Send updated confluence page to server?

I am new to the forum. Landed here as we are on our journey to take our confluence development skills to other level. We have confluence page that is displayed on the client side that we edited and would like to update that page on the server side. So far we have not landed on any concrete solution on how to achieve this function. We are using plugins that read the confluence page template from the server side and all our updates at the client side are of no use till we push them to server side.

Please include the link of those similar issues if you know any or your suggestion would be highly appreciated.

Are you talking about two different Confluence instances, and you want to publish from one to the other?
