SNG7 is a 64 bit only operating system. Unfortunately, It is not possible to convert a 32 bit operating system to 64 on the fly, If you are currently running a 32 bit operating system, the simplest way to upgrade is to use the FreePBX Conversion tool, which will allow you to do a live backup of a running machine and restore it to a new 14 machines.

Upgrading a Hyper-V system is explicitly blacklisted due to compatibility issues when changing from a Non-UEFI image to a UEFI capable image. The only way to upgrade a machine running on HyperV is to create a new machine, and then use the FreePBX Conversion Tool to migrate your complete machine to a new one.  This is not a destructive process, and can be run on against a production machine at any time.


The Upgrade is managed by a RPM.  Simply install the RPM with the  following command

Code Block
yum -y install
