(IIRC, the upgrade from FreePBX 12 to 13 has to be done manually even with System Admin Pro…)
If you don’t, you need to run each of the scripts (which have not been run, see Upgrade Option 1 to determine where you should start) on that page in order to bring it to the latest FreePBX 12 version and then run
Hello, I have obtained an error, it seems that I do not have the distro but: FreePBX 12.0.76.4 ‘VoIP Server’
[root@localhost /]# /root/upgradescripts/upgrade-10.13.66-1.sh
cat: /etc/schmooze/pbx-version: No such file or directory
Check to make sure this is a FreePBX Distro system before executing
This does not appears to be a FreePBX Distro system as it has no Distro Version file
[root@localhost /]# cat /etc/asterisk/freepbxdistro-version
cat: /etc/asterisk/freepbxdistro-version: No such file or directory
[root@localhost /]# cat /etc/schmooze/pbx-version
cat: /etc/schmooze/pbx-version: No such file or directory
That said, one of them could be a VM (virtual machine) or an old which you would destroy after…
You could use your current server as source and a VM (or a PC) as destination to upgrade your installation, back it up and then, once you are sure everything works, install the FreePBX 13 distro on your current server and restore the upgraded config.
