I am trying to upgrade our Zend Server 6.3 IBM i free edition and researching about the new version of Zend searver. Zend server 8 looks like that it already came out from the previous Beta version to now the real version. Then it has two options as PHP5.5 and PHP5.6. Why are there the two versions? Which version do we need to pick? Is it easy enough to upgrade from version 6.X to 8 if you have an experience? Is it possible to upgrade from 6.3 free edition to 8 free edition if there is a free version of 8?
Thanks,
The best is to read the manual at the zend server docs. You can not run more then one PHP version at the same time. Hence the different versions. And I would go for PHP 5.6
