Upgrading Drupal

I have been working on upgrading our D5 site to D6. One problem I am seeing is that where D5 would ignore legacy SSI code in content pasted in from our old (non-Drupal) website, D6 seems to be displaying this code. I know the proper thing would be to go through and clean SSI code out of these pages, but there are a *lot* of pages. Is there a configuration setting to enable D6 to ignore SSI code? Alternatively, does anyone have a suggestion for automating the process of scrubbing the pages? A regexp, perhaps?

This might be silly, but I couldn't find info on this when I searched. What would be involved in upgrading a Drupal installation from PHP 4 to PHP 5? We're still on Drupal 6.12, so we need to upgrade to 6.13 anyway.

After following EVERY upgrade step I am able to get the web site back up, however the module page does not load all I get is a "blank page" any assistance would be very much appreciated

After upgrading to Drupal 6, my site is throwing up an Access Denied error for the homepage for anonymous users only. They can access ANY OTHER PAGE on the site but NOT the homepage. The site is located here:

I have checked access control and permissions time and time again and see no reason why it's doing this.

We are upgrading to Drupal 6.13 and our site has been down for almost TWO weeks. The site is on a share enviromanme using linux. We experience errors at the initial stage of executing the update.php that won't allow us to proceed - register_globals needs to be disable along with mbstring.http_input.
