Thread:Project:Support desk/PHP version error when upgrading from 1.17 to 1.21/reply (10)

We tried to dig deeper into updating to 5.3, but ran into big problems. The primary purpose of our server is to run an Invision Power Board forum.

But, the forum crashes when PHP 5.3 is being used. The forum required Zend Optimizer. Zend Optimizer doesn't exist for PHP 5.3. The product was renamed ZendGuard when it was released for PHP 5.3. However, ZendGuard cannot load files that were encoded for Zend Optimizer, and vice versa -- they're effectively two separate products. If you've got an application that was encoded for Zend Optimizer, you're stuck on PHP 5.2.

So we cannot update our Wiki to a version requiring a version of PHP beyond 5.2.

What are our options? We have a separate, modern, virgin version Wiki installed. Should I be trying to export from the old Wiki and import into the new Wiki or trying to update the old Wiki in some other way (like manually)?
