To get to the “Tools” page, you have to go thru the “Dashboard > Obituaries” sub-menu on the top of the page.
This tool will allow you to update guestbook URLs and obit photo urls to your new url. Only use this tool if you have migrated your platform to a new url. This is a traditional search and replace so please use exactly what you want to replace. Please note the example below. This will replace both obit photos and guestbook photos!
