Question Moving from 3.8 to 4.2


I need your advice on how to upgrade to 4.2.5
Testing on local PC using XAMPP:

Old Forum:
PHP Version: 5.6.32
Myadmin: 4.7.4
Vbulletin: 3.8.11
Custom syles
Runs perfect!

New forum:
Migrating database to
PHP 7.1.1
Myadmin: 4.6.5
Vbulletin: 4.2.5

1. Do I create a new database and install VB 4.2.5 first then import vb 3.8 backup to it?
2. or Create new data base, restore vb 3.8 back up ?
3. In all cases when installing vb 4.2.5 it over writes the entire database tables.
4. I wish to keep the vb3.8. customized style, is there a tool to modify/upgrade the style to vb4.2?

If all goes well, I'll be upgrading to VB5

You do not need amp. You can just back up and make a test site in a directory on your server if you wish. Run the upgrade script there and fix the theming, etc.

Or is your plan to build the site fresh in 4.2 and then import? Either method will work.

Basically create your new vbulletin site and use Impex to import from the old files and database.

Let us take care of your forum, seo, seo reports, maintenance, what ever you need.

1. Create new, there is no reason for an import.
2. Create new & import your backup, from the cmd line prefebly as the new server could time out importing thru phpmyadmin, you may have to tweak phps timeouts via php.ini.
3. You will run the upgrade script after uploading the new vb 4.x.x series php files to the server.
4. You should build a new style based off the old style, there are MANY things a 3.8 style wont have for functionality in the templates.

New and clean is always best, vb4 is way different than vb3
