Updated php.ini not populated to php.ini of individual domain names after Zend installation

SUMMARY: When upgrading to a newer version of Zend Optimizer www.zend.com , the updated php.ini isn't populated to the php.ini of each individual domain names. Therefore, if you do a phpinfo() at any of the existing domain names, you will get the old version Zend.

DETAILS:
I previousy installed Zend Optimizer 2.6.2 on my server. I then upgraded it to version 3.2.8. The upgrade process is simply installing the new version over the old one (or, as if you are installing it for the first time)

The phpinfo() of an existing domain name says:

...which isn't right. When I check the php.ini at /usr/local/Zend/etc/ I got the correct version:

************************************************************ **
[Zend]
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimiz er-3.2.8
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Opti mizer_TS-3.2.8
zend_optimizer.version=3.2.8

zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_T S.so
************************************************************ **

I dug further and realise that Virtualmin creates a php.ini for each domain name. When I upgrade Zend Optimizer, the new information isn't populated to the php.ini of those domain names already created.

SOLUTION: I manually added the above lines to the php.ini of each domain names already created, and commented out the old version. So now phpinfo() for the existing domain names shows:
