Upgrading from 4.2.3 to 4.2.5
 

What steps do I need to take to upgrade from 4.2.3 Patch Level 2 to the newest 4.2.5? Is it worth the upgrade?

I've already did a complete backup of the home directory and database.

Thanks in advance!

1. Backup everything.
2. Overwrite current files with new files.
3. Go to /install/upgrade.php and follow steps.

It's definitely worth the upgrade, I recommend to use PHP 7 for a significant performance boost.

It is worth if you want to use PHP 7 for vB 4.
The choice is yours and just some minutes you can upgrade to 4.2.5

Anyone here ?
I will upgrade my site from 4.2.3 ?to 4.2.5 but I have worry about my plugin and postbits.

If I say overwrite all of them, isnt delete my plugin and postbit and some changes in css or my theme

Your installed products/plugins will not be overwritten or deleted, and any customized templates will also not be overwritten. You will simply be warned that they may be out of date. I left my customized templates as they were with no bad effects.

With vB 4.2.5, you will no longer have the option to use cookie based thread read marking, but the database marking is vastly superior in my opinion and I was using it for years anyway.

Upgrading from 4.2.3 to 4.2.5 should go smoothly. Of course, be sure to backup your site first.

Full backup or sql backup is enough for me ?
Thanks for your advance.

Also when I start upgrade, the php version is important ?

My php version is 5.4 now.

Which version should I choose??

You can use up to 7.1 for vbulletin itself running 4.2.5

7.1 may break a addon/product test after implementing 7.1 to verify you have no errors, you may be able to disable display_errors if any warnings popup though

5.6 should be fine for any addon currently made for 4.2.5, BUT 5.6 is EOL, so id at least run 7.0

I will try it, hope everythings will work.
Latest question, my root directory backup is more than 40 gb. Because there is picture upload script inside and lots of picture.

So only sql backup enougf for me, if cant make it, possible ro recovery my forum?

Back up the home dir with tar/gzip etc

Images wont be removed because you're upgrading vbulletin.

Dear snakes, I owerwrite files and folders but when I want to start upgrade.php, it gives an error

500 Error. Internal Server Error.

Any way for solution?
