Replacing F5 new ifile html file

Hi,

I need to replace the existing ifile (for example: "prod.html" file) with a new ifile that has the same file name (prod.html) in F5 LTM. Please provide the steps to upload the new "prod.html" file to F5 LTM and how to replace the existing file with the new one. Since there are multiple irules referencing the same ifile, renaming the ifile is not an option; therefore, the requirement is to replace the HTML file with the new one. Please share the recommended steps so that I can create a change plan for this.
