We're upgrading from Bootstrap 2 to 3. Now I need to replace CSS classes in the body fields of many nodes. This needs to be done in at least 5 sites. What is a good way to replace text in all nodes of a site?
Ideally I'd do it with something like
drush replace old_str new_str. Found one thing from 2009 that didn't work at all and then I found
drush sar, which didn't do the job either.
