It is strongly recommended that a full backup of the system (13 ,14 or 15) be made prior to the upgrade steps below. If necessary, this backup can be used as a restore point to a new install. Note also that the new Backup and Restore module in FreePBX 16 allows restores of backups made by previous versions.

Upgrade to FreePBX 16 from FreePBX 13/14

The recommended path from FreePBX 13/14 to FreePBX-16 is to use the "Backup & Restore" functionality to take a Backup from the working FreePBX-13/14 system and then restore to newly installed FreePBX-16 system.

The following steps will have you up and running on a FreePBX-16 system with the same configuration as your existing FreePBX-13/14 system. 

  1. Take Backup of your FreePBX-13/14 System.

    1. Take full backup of your FreePBX-13/14 system using Backup & Restore module of FreePBX-13/14.  Please refer to Using the Backup module for further details of how to configure and take full backup of your 13/14 system.

  2. Install FreePBX-16 on another server.

    1. Install latest available FreePBX-16 ISO from https://www.freepbx.org/downloads/  to another server. Please refer to Installing SNG7 Official Distro for more details about the installation process.

  3. Activate FreePBX-16 

    1.  Once FreePBX-16 installation is done, activate your FreePBX-16. Please refer to System Admin - Activation for more details about the system activation process.

  4. Upgrade all FreePBX-16 modules to current 

    1. After activation , FreePBX will show you a pop up with a list of available module updates. Otherwise you can check yourself by using "Check Online" function in Module Admin. Please refer to Updates#ModuleUpdates for more details.

  5. Restore 

    1. Please note that Backup & Restore has been completely re-designed in FreePBX-15/FreePBX-16 so you will see GUI differences in the way it used to work in FreePBX-13/14 vs FreePBX-15/FreePBX-16.

    2. Please refer to Backup and Restore FreePBX 15+ for more about the FreePBX-15/FreEPBX-16 Backup & Restore module. 

    3. We can restore the configurations by uploading the FreePBX-13/14 generated configuration backup to "FreePBX GUI → Admin → Backup & Restore → Restore tab".

    4. After a successful restore , your FreePBX-13/14 is successfully replicated to new FreePBX-16.
