ImpEx stalls importing threads from phpBB2

[kirstyd]

Hi

I'm trying to import a phpBB2.0.16 forum to vBulletin 3.0.7 using ImpEx.

If I try to import the users 500 at a time, nothing happens: the page stays the same after I click "continue" and nothing seems to be happening in mysql processes. If I try to go back to the import page it just shows the module names with no buttons to press to do anything. I've discovered by trial and error that I *can* import the users up to 300 at a time, any higher and nothing happens.

So I eventually get all 100 000 of my users imported.

Then I get to importing threads and seem to have the same problem. Except even if I change the settings right down to importing 1 thread at a time I can't get anything to happen! Also the only way I can get back to try importing the threads again is to delete everything and start over importing all 100k of users again... a bit tedious!

Any ideas? I have about 800 000 posts in 80 000 threads to import.

thanks

What is your PHP memory settings and the specs of your server for a board of that size ?

[kirstyd]

We've got 2Gb of memory on the server, but memory_limit is set to 8Mb, I'll try upping it and see if I get anywhere.

With a board that size, just for the import I'd set it to 512 or something, the threads array alone for post imports is going to be huge.
