Do any large vb boards run VW4?

Are there any medium to large boards running VW4?
I would like to see, because I want to review if one of the following releases can be used to upgrade my vbulletin big board from VW3 to VW4.

Does the import / upgrade function work flawlessly for vb?

I remember helping a customer who had 5 or 6 million posts. I don't remember which board it was or how VW4 has performed for them since that time.

In general, though, VaultWiki 4 should have better performance than the same page on VaultWiki 3.

I cannot say if that function is flawless. I have yet to try the vB3 test you provided, as I was waiting for the import ID problem to be fixed (which it recently was). As it was a major change, I suspect it introduced some new issues.

I haven't looked into this yet, since we are currently trying to refactor some parts of our site that are still using old vB3 code, and change them not to vB4 code, but to VW4 code so that we can migrate to XenForo if we decide to. (We were ahead of schedule on a new release).

I'm sure VW4 will have good performance for big boards. I'm concerned about the migration / data loss / bugs that may be encountered when moving from VW3 to VW4.
Please check your PMs to see if you can find the big board.
