3.8.9-4.2.5 Upgrade Time Estimate

[Kestryll]

I have a forum with the following stats: Threads: 1,291,566, Posts: 19,532,143, Members: 292,095

I'm currently running vBulletin 3.8.9 and obviously need to upgrade. I'm not a fan of vB5 at all so I'd be looking at vB4



How long would an upgrade with those numbers take and what's the likelihood of problems?




Thanks!

You really can't say exactly how long this would take.
From hours to days. It depends heavily on the performance of your server.

The mandatory rebuilt of various counters (thread and forum information) and of the search index will be the most time consuming tasks.

You really should to a test upgrade on the same server with a copy of your forum to see how it goes.
