We are attempting to determine our options as to our current installation of Zen Cart 1.2.5. It is and has been running just fine on a Linux server with PHP 4.4.7 installed. One of our four domains on the server is a vBulletin forum. We have been informed by vBulletin that their upcoming release, version 3.7, will require PHP 5 to run.

Questions:

1. Will Zen Cart 1.2.5 run correctly if we upgrade our PHP 4.4.7 to PHP 5?

2. If we decide to upgrade our Zen Cart installation, is there anyone offering installation/upgrading services for hire who would be recommended?

My thanks for any and all help.
