Help with Cleaner

[MarcFBR]

I am looking for some help with the last leg of the conversion process to the vB software, specifically running the Cleaner.php utility. Basically, after numerous attempts in a variety of different ways, I've really just come to the point where its clear that my server really just can't handle running the utility out of the box, likely due to low physical resources and numerous (over 200,000) posts that need to be effected in the cleaning process, so what ends up happening is that cleaner just hangs for a bit and times out.

As a result of this, I believe the only solution available is to find some way to delay the cleaner process, as Impex does by splitting each process into a cycle of X number of posts, rather than attempting to make the effort in one sitting, but as it is, the person I usually work with to do this sort of stuff is stumped on how to go about implementing what Impex does, since having to deal with enormous software backends is really a new thing for both of us, and especially of working with vBulletin, since we're freshly making the transition from SMF, and with the amount of work its taken to just get the forum back up and running as-is was enough that we've hit a point where we're running out out of steam just trying to figure everything out.

With the amount of experience the coders on this forum seem to have, it would be amazing if a solution to this problem could be found for us. I mean, at this point it's a matter of finding a solution, or giving up on it, and I've been obsessing over this issue a little too much to let it go now.

Thanks in advance.
