I recently moved a blog using galleries in posts from one server (where it was running version 3.2 and template 2010) to a server where I could run 3.5 and template 2012. Since I had just successfully transferred a similar blog which used regular images instead of galleries, I was surprised to find that the galleries didn't import with the posts, even though I checked "attach media."
I'd really love to preserve the date and caption information for the galleries, plus save myself the labor of importing the images manually - what can I try to reconnect my galleries and posts. Re-import? Move the entire database? Or is there another solution?
