Downgrading vBulletin Versions

[Eric E.]

Hello, I'm Eric E. Recently, I had the version 3.6.8 of vBulletin and I wanted to upgrade to 3.7.0. Now, after I upgraded to 3.7.0, I found out that the version 3.7.0 has an error in profiles. So, I want to downgrade back down to 3.6.8 but, vBulletin told my friend that there's no way to downgrade which is a lie and there actually is a way but, I just don't know how. If they if is a way or not, can you please inform me? If there is a way, please tell me how to downgrade from 3.7.0 Release Candidate 3 to 3.6.8 or 3.6.9, please. Thank You and have a nice day!

There is no error in the profile...you need to revert your templates.

[King Kovifor]

Revert your templates and there is no supported way to downgrade except to revert to a back up.

I have a backup of when I had a version of 3.6.8, is there a way I can downgrade?

Eric E.

Didn't you hear us...Revert your templates...that will fix the problem.

[Eric E.]

What do you mean by reverting? Re-installing it?

Eric E.

[King Kovifor]

There is no need to be mean there Bradley. Go into your style manager and then click on [Revert] next to the memberinfo_ templates.

[Eric E.]

I revert it and it's still doing it.....

[King Kovifor]

What errors are you getting?

[Eric E.]

Just forget it. Can you just tell me exactly how to downgrade with the 3.6.8 backup I took before I upgraded?

Eric E.

[King Kovifor]

You would need to overwrite your database with the back up and then re-upload vB 3.6 files.

[Eric E.]

You mean....

I inset the backup in MySQL, then I install all the 3.6.8 files, then I add the backup to my FTP?

Eric E.

[King Kovifor]

You would use a program that deals with your database (and allows uploading of .sql files). Upload that to your forum's database (overwriting all the tables before). Then upload the 3.6.8 PL2 files using your FTP client.

[Eric E.]

So....I upload a backup normally like usual then I upload the 3.6.8 files?

Eric E.

[King Kovifor]

Yes.

Maybe we can help you figure out the error problem. Are you getting a database error? Can you paste it here?

The only way to downgrade is put your site back to how it was before the upgrade. That means put back all the old 3.6.8 files (php files and attachments, avatars, etc if they are in the filesystem) and upload the backed-up 3.6.8 database. Make sure you have nothing left from your 3.7 upgrade. You cannot simply downgrade a database that has already been upgraded to 3.7 (OK, you could go through all the upgrade scripts and undo all the steps they took to change your database, but who knows how long or how easy that would be).

edit: Wow, you guys posted a lot since I started to write my reply. It's a little old now, sorry.

[Eric E.]

Okay, I highly doubt it, but, I'll still try it, Lol.

Eric E.

Are you posting the error? Cause we can most likely help you fix it if you want to stay with vB 3.7!

Lynne, it's cool.

[Eric E.]

I already got it down to 3.6.8 by restarting my whole forum. I'm uploading my backup now.
