Can You Change The Editor On Existing Blog Posts?

Hello,

I have a number pf blogs post that have been created with the easyblog composer editor. I am finding this editor very limiting and somewhat buggy when doing simple formatting such as bullet points and indentions. I want to change the editors of all those post to JCE but I am only seeing this work when I create a new post. I Hope I do not need to recreate dozens of post just to have a better editor. Please advise.

Thanks,
Derek
