Changing From Tinymce To Redactor

If I change from TinyMCE to Redactor in the Global Settings section, will anything break?

What I mean is that I use tables, videos, pictures and links, etc.. I am afraid if I try this, I may not be able to revert back easily if I find thinks are broken.

On this forum there were messages about incorrect processing of some HTML tags by different WYSIWYG editors. So make database dump just in case
