Upgrade Community from 4.2.7 to 4.7.x [possible PHP issues]

[JankaR]

Hello, I renewed my license after 4 years, so before I hit anything in upgrade proccess, what is good to know?

4.2.7 is not compatible with PHP 8 and 4.7.x needs at least PHP 8.

Is upgrade script able work under php 7.4? Or is there other way how to successfull upgrade? Thanks.

No, it will not work under php 7.4. because as you already mentioned, the minimum php version for the latest Ipb version requires php 8.

You should upgrade first your php version and then you can run the upgrader.

This not possible, admin works only under PHP 7.4, under PHP 8.0 I got lot of fatal and deprecated errors.

You can’t use the updater in the ACP because of how far behind you are. 

You need to update all of your third party resources.

Switch to a default theme. 

Download a copy of the latest IPB files from your client area.

Make sure you are running PHP 8.0/8.1.

Run the IPB compatibility script to make sure your new PHP version has all of the required modules.

Upload the files from the client area to your website.

Run domain.com/admin/upgrade

Switch back to your original theme if it’s compatible with the newest version.

I manually uploaded all files via FTP

Switched to PHP 8.1

Then ran /admin/upgrade/

This went without any issues

After upgrade in ACP I cleared all caches

On board index I got some fatal errors, but after removing some Page's templates which I created long time ago and refreshing board index page, errors vanished.

Looks like everything goes good, thanks Randy.

Awesome!  I’m glad you were able to get the site upgraded.
