Issue upgrading from 12 to 13

I used the upgrade tool to go from 12 to 13. During that install I got the following error

> ERROR: Try running this manually on the CLI to finish: 'amportal && fwconsole ma upgradeall'

I then went to CLI and ran the command. The upgrade finished with the warning:

  fopen(/etc/asterisk/ failed to open stream: Too many open files 

Is this a big problem? Or can I ignore this?

A little more info.

Once in the GUI, I am not able to apply config. I get the error:

exit: 1
Whoops\Exception\ErrorException: symlink(): Permission denied in file /var/www/html/admin/modules/ucp/Ucp.class.php on line 547

Once you fix that issue then run “amportal && fwconsole ma upgradeall”

Then run fwconsole chown.

The upgrade tool originally failed because you have too many open files.

Thank you so much! That fixed it.
