If your Swords are pretty big they will have a very large root system. Depending how far back you're trying to move them you can either just slide them through your substrate to avoid pulling the roots out completely or you can pull them out all the way and then replant. Getting all the roots back into the substrate on a large Sword can be a pain. Basically just make sure the roots are completely buried when you're done moving them.... It's probably going to be messy no matter what.
