We just purchased XF. I will be migrating a matured vb installation (it has been running for 7 years and although we do prune from time to time, there's still well over a million posts). When i first picked up the xf I just thought I'd see a raw installation, so I created a subdirectory and installed there. I have two questions. 1. should I change the way i set this up? i can create a different domain to install this to, so when i migrate the paths wouldn't change (as long as they're relative), or is it simple to change paths and move the forum from a sub folder to the root after I'm done? 2. doing an import. this is where I'm concerned. The best way to do this would be to shut off my current forum, then begin the migration, because I'd not lose any data from the live board. But our db server is not on the same box, we have several machines co-located, and our DB server is actually residing on Ec2 right now as an instance. my concern is this is going to9 take a very long time. Now, to prepare, I changed the current forum to move off attachments to the filesystem and not store them in the DB. the same for ALL images. I also do not allow uploads to the current install, though that will change. Even though I've done this, the existing db is still just over 1gb. Now I know much of this is dependant on resources, but i would like to know it a.) the default vb4 import is the right tool, i saw someone created an add-on for migrating big boards, but frankly $150 seems exorbitant for a on time use tool. However, it raises questions, that if someone went to the trouble, does that mean the default importer is not a solid tool? and b.) is this likely going to take a day or more to import? if anyone could help here, it might make my transition much smoother, and I'd really appreciate it. Thanks!
