If it's OldFolder to new-folder those are entirely different URLs with no way to automate it. Unless you have a lot of names in the form "blahblahfolder" with a recurring element; then there might be a pattern.
Show us what you've got and we'll help you with details. The big question is just how many pages are involved, and how many permutations of basic patterns such as lowline vs. hyphen. This will determine whether it's better to keep it all in htaccess, or to rewrite everything to a php page that does the lookups and transformations and then issues a 301 of its own.
I have five different folders with upper case letters.
Folder ServiceBasics would change to service-basics. Folder Archive to archive, Company to company, ServiceTools to service-tools, PDF to pdf etc
Under each folder there are like 10-15 pages.
Is it the same changing url (path to page) and page name for SEO?
What would be better for SERP - changing just folder upper to lower case or changing the page name too?
