migrating confluence database to new instance

[mydogspot]

I've read the documentation for migrating confluence db to a new database, but it doesn't quite answer my question.  I need to move our existing confluence mysql instance to a new mysql instance because the old one is choking.  I tried mysqldump and then importing the database into the new instance.  I changed the db server name in confluence.cfg.xml and I can see that I have a connection successfully hitting the new mysql instance, but my confluence page is not showing up.  It's not timing out or anything, just getting a blank page.  Did I miss something, or is trying export/import not kosher?

You've done most of the right stuff, possibly all of it.

But you need to read the application log to see what is failing.
