Thank you, yes. A rebake fixed it. We’re all set.
In hindsight, if I had to do it again, I’d either just use the slow method, or follow @mmayo’s “quick and dirty route” minus the remap, but plus a rebake. Once the rebake was done, I’d delete the local uploads folder.
That way, the site would be 100% functional the whole time. As it was, we were up and running, but images in posts didn’t display correctly until the posts were rebaked.
Thanks,
Gunnar
