Largest possible export via web
 

I've got a long running forum hosted with a company who have gone under and refuse to answer any calls/emails/texts.

I do not have any command line access to my forum.

The only way I can conceivably get it back is by doing a database dump via the admincp. I'm aware this is a very limited option and I estimate the total size of the forum to be 1gb+.

Is this doable via the admincp or will it just time out?

If it will time out, and I want to move my forum to another host, can I, for example, just export the users and posts tables and them re-import them to another installation of VB?

Currently running VB 3.6.8

Any help would be much appreciated, thanks. I'd hate to lose nearly 8 years of a forum.
