The good news is that the new server is working OK. The new server is more up to date, bigger, and supposedly better ...... and it supports the latest phpBB forum software, which is supposed to fix a lot of bugs.
The bad news is that I was not able to figure out how to import the database from the old forum. In theory, there is a way to import the old database, but it gave me nothing but errors.
There's a lot of good data in the old forum and I backed up the database, so if I have to, I'll manually repost the more worthwhile threads, as time allows.
Member information from the old forum was also lost, so you'll have to register before posting.
