We have created a new set of pages to replace the old set currently existing on our site. We would like to change the file directory name, file name of the pages too. Generally what normally should be done is to set a 301 server redirect to direct the old pages to the new, but the problems is, my hosting company says they cannot set the redirect because the old urls have "_" in them. I wouldn't want to put a regular html redirect in them since they may hurt my exsiting rankings(right?). I wouldn't want to put a static link for my customers to click on everytime they come upon an old page either. Any ideas on what I should do? Please advise, thanks!
