vb 3.8 to IPS 4.0 Converter?

The converters are an app, just like forums, gallery etc, they are pretty solid right now as far as bugs, and why I would recommend converting now, waiting for a solid 4.0 converter with all the many items that have to be updated, then test, then released, may take a while for them to be as good as they are now with the 347 series.

​But updating via 3.4.7 to 4.0 from VB3.8 means a very long conversion time for a large forum community.  This route means double of the conversion time and maybe a couple of days offline ??  I would like to have a CLI version of the database converter, that should work much faster than the php-update process (??)

But if we want to save our post history which is a feature in vB, and not in 3.4.7, we have to wait.

Maybe it's worth losing that to get a better conversion.

PS. Does the new post history feature in IP have a time/purge feature? Like, keep for a year only, etc? If so I would probably use that and it would make me more comfortable converting, seeing as I would lose them eventually.

Thanks!

​About 75.000 members and around 500.000 posts....

That should be about 3-5 hour conversion at most from start to finish, depending on your server strength etc. So again I would recommend converting now, then upgrading to 4.0 once it's been released as final etc.

​We don't convert post history currently and I'm not sure if that is something that can even be converted with 4.0 at this time, it would be a 50/50 guess at this point, and only time will tell.

A lot of vb forums used the "like" feature of the vbseo addon. Do you think the converter will ever be able to convert those "likes" too? 

I want to convert my vb4.2.2 to ips4 when it´s final, too. Until I read this thread I doubted if the conversion to ips3.4.7 and afterwards to ips4is the right way. But now I understand your point of view Rhett.

Especially I hoped that there will be a part in the ips4 converter that can handle all of my thread-prefixes.

​I converted my forum with 100k members and 10 million posts and it took exactly 24 hours. This is on a 24 core database server, with 128GB ram and a Fusion IO raid 0 setup. By the time all the indexing was completely done, it was exactly 24 hours. Thats why I am contemplating going to 4.0 directly as I don't want to deal with the downtime twice. On top of that I am on a load balanced setup where there are 5 web servers serving content and IPS 3.x is not very load balancer friendly.

If you can spare it, why not take one of the load balance servers "offline" do the upgrade there and then push the new settings out to the others once all done? That should eliminate any downtime and actually a benefit of load balancing servers. 

Would love to be in that position :laugh:

Sure, thats exactly what I did, but the problem is that it takes 24 hours for the conversion to complete. So the site has to be either down for 24 hours, or I lose 24 hours of posting which is a lot of data. Then after all that, IPS 3.x writes to the local drives of the server, so you have to either rysnc the data to all web servers or use a NFS share. Then more downtime when upgrading to 4.0. So, I would rather directly upgrade to 4.0 which is a lot more cluster friendly.

Purchased IPB 4, intending to go from vb 3.8 to IPB 4.  This is the only thread I've found on the subject so far.  IPB 4 was released April 9 as "fully supported", I am hoping that the vb 3.8 converter app is available by now?

​The current recommended path is to convert to 3.4 and upgrade to 4.0

Hope so. If you go from vB to IP 3.4 to 4 the redirect script doesn't work so you lose all redirects in content. Dead links. This was verified by IPS so waiting for the converter.

​We do have some redirection scripts available as previously mentioned on the community (they should be included with the next converter update). In the meantime you can submit a ticket asking for them.

I know redirects work in 3.4 but once you jump to 4 they stop. So you are saying you can get them to work again? I'd rather wait for the 4 converter. Do you have an estimated release date? 

Post history is lost too since 3.4 does not have this as a feature but vB and IPS 4 do.

​You can wait if you want. "When it's ready" is when it's ready.

We have updated scripts that provide redirection functionality for people that have upgraded from 3.4

IPS is saying the only supported method available is going from vb 3.8 to ipb 3.x, then from ipb 3.x to ipb 4.x.  I am wondering if anyone with a large board has done just that, with success?  I guess what I am asking is this:  is this "supported" method really the best method, or are things missed during the conversion and thus it would be better to wait for the official ipb 4.x conversion route?

They should at least offer the converter for beta testers, surely there will be bugs when it comes out. We could be reporting them now.

​Except I don't believe they've started coding it yet.  I guess I'll be going the IPB 3.x route instead, and hoping it works 100%.

I am guessing there is no converter. It's likely planned but I've not heard one serious iota regarding a new converter.  Probably the full team has been dedicated to the successful launch of IPB4 and hasn't had opportunity to put some serious bandwidth into the converter.  I wouldn't hold my breath if I were you.
