In this particular case I didn’t find any issues, just followed the following instructions and the upgrade went just fine:
1) fwconsole ma downloadinstall http://mirror1.freepbx.org/modules/packages/versionupgrade/versionupgrade-15.0.42.tgz
2) fwconsole ma upgradeall
3) fwconsole chown
4) fwconsole versionupgrade --check (if everything is OK then go to 5)
5) fwconsole versionupgrade --upgrade
If you have another instance with the error, please share it on our case Jeremy, so I can investigate
Yeah, I did the same and had what sounds like very similar issues.
in the end, I had to resort to installing 16 from scratch then restoring a backup from the prior 15 system. That’s when the DB errors started.
When I would attempt to save a template in EPM a db field unknown error would pop up but the template would be written (at least in the UI). The issue was it wasn’t writing the config files based on that template.
Once I got the proper fields added into the db and upgraded to the edge version of EPM the config files were written.
I made sure everything was up to date. (ran fwconsole ma upgradeall and yum update
I disabled the firewall (I needed it off for Sergio,due to VPN not starting)
I also ran the following, which was run on another machine Sergio upgraded for me:
sysctl -w vm.drop_caches=3
We are also using versionupgrade-15.0.42
Doing these steps, I can successfully upgrade 15 to 16.
