Thanks Gizmo-

Well, Rick said Groupee would do it. Looks like a very fair price to me, and you know you'd be safe in their hands

$199 vs losing 100k posts (& stress etc.) = no brainer

Hi embryo,

Well I don't have experience with the old 6.4 and CGI but if it's running on IIS on Server 2003 I'm sure I can probably assist you with it.

Is this your own Server or is it possible to Remote Desktop access with Admin rights on it, at least initially and then you can remove those rights after the work is done.

I'll reply to your PM and we can go from there. Though Groupee might be able to get you up and running as well since they should be conversant in Windows platforms as well. If not let me know.

I've run .classic on IIS for years (we had UBBDev.com on IIS for most of its formative years ). I've run .classic since the 4 series and .threads since the 4 series. I've upgraded .classic sites to UBB.threads many many times. If groupee can't get to it, pm me details about what you're wanting and I can do it.

If your permissions can be set correctly it is a simple painless process to upgrade to threads. I have done it myself many times and I am no expert by any means. If you pay someone you will still need to deal with your host to correct permission issues or add mysql to your hosting package if they are incorrect.
Depending on how big your forum is all it takes is some time to backup and upload some files.
You can always do a trial upgrade and see what happens. Then pay for support if you have issues.
