Currently we are serving details to our visitors through a database oriented website. Visitor selects around 5 Level options

E.g. Level One: book
 Level Two: Chapter
 Level Three: Topic

Now we want to convert all the details in pure html contents so there will be around 20000 pages. (Our purpose of doing this is that the search engines will be able to crawl all the contents.)

If we convert Database contents into html pages and upload them all to our website in a single stroke, will there be any problem with popular search engines like google and yahoo?
