Hi, In the newest version of the blog software I use there is support for search engine friendly URLs using mod_rewrite. The problem that I have is that the pages in this blog have already reached a PR6 and if I just simply upgrade the software and turn on the url rewriting all those pages will loose their PR6. Is there a solution? For example should I build a sitemap with all the old URLs and post that on the blog so the pages are still accessable via their old URLs until the new ones take effect? Advise please! Thanks, Gary
