Centos 5 or Centos 6.5

[Camilo]

I would appreciate any help on this before I go further with ERPNext.

I would like to install it and implement my self on a  virtual CentOS server. Since I have Centos 5 and I read about CentOS 6, I wonder if it is necessary to upgrade my System and if it makes a diference for ERPNext funktionality.

Thanks,

Camilo
