Attempted again to switch from Asterisk 10 to 11, no go, help!

Seems to complete the switch but when it tries to restart Asterisk it repeatably halts with “code 1”. I have to say that that is not a very useful error message.

How do I figure out what it is stumbling over, what code 1 means?

Thanks

Erase the config in etc/asterisk with the letter cel in them filename

Its not a error code we can control. Its a Asterisk error code.
