I would guess 2 hours.Also approx how long will it take to import. My phpbb forum has about 200k posts 25k threads and 12k members.
I can do a MyBB import for you. I have a system setup for MyBB that is very thorough:btw does the built in importer work for mybb?
Can someone verify this information and answer the last question?I know how to get to phpMyAdmin, from there I can click into the database named after my site, then "Operations" there seems to be a "Copy database to". Is this how you would make a backup?
If so after that how do I switch between two databases?
