Have a FreePBX 18.104.22.168 built on the distro to which I have tried a few times to upgrade to 14 using the instructions found at https://wiki.freepbx.org/display/PPS/Upgrading+from+FreePBX+10.13.66+to+SNG7
When the upgrade was complete, it appeared to be fine. When the business opened people were unable to login to the queues, inbound calls would fail. I had seen in CLI messages something like from-queue not found in context … Outbound calls could not be made.
I had to recreate a FreePBX 13 VM and then run a restore from our FTP server to get the calls working again.
At this point unsure of what would change config files like extensions_additional.conf during the upgrade or, changing other files that might cause this.
Perhaps someone else has run into the same issue and knows what the cause is.
