VTE 15.05 / 15.10... will work on Ubuntu 14.04 LTS?

Hi,
I installed VTECRM version 4.5 about 2 years ago...
In help section it was specified it would be able to run on Ubuntu 12.04 "out of the box".
Now I upgraded to version 15.05... and I'm planning to upgrade to 15.10 soon.
Can I upgrade my Ubuntu version to 14.04 LTS too?
Or I will not be able to run the CRM?
I run Apache 2.2.22 , MySQL version 5.5.46 and PHP 5.3.10 (Ubuntu).
Thank you.
Giuseppe

... any help???

Hello Giuseppe, I suggest you to upgrade vte to 15.10 and than you can upgrade ubuntu to 14.04 because the version 15.05 does not support php 5.5.

OK!
Very kind.

Regards, have a nice day.
Giuseppe
