By bigboards I mean lots of users and threads/posts. I have 400k users and almost 2million posts, and I cannot import smoothly. My internet is not the most reliable of things, and compounded with having the server in the US when I'm in Australia results in many packets lost which in tern mean the upgrade process does not continue because the browser shows an error (timing out). Is there some sort of script that can be run from the server itself (I have a dedicated server)? It should be quicker and more reliable. I'm also wondering how do you make it seamless or reduce the downtime? Importing the table script took me over 12 hours (2Gbs), albeit the dropping pages did not help the process. You then have to add private messages, visitor messages, and the users themselves.
