[Asterisk-Users] Asterisk upgrade on production box

[Nik Martin]

What is the best way to upgrade a production asterisk box?  make upgrade?  I
don't want my configs messed with, and need the process to go as smooth as
possible.  I fetched and built a new kernel last night, but haven't rebooted
into it.  I'll do that tonight, and then want to quickly upgrade to the
latest asterisk (mainly for zttest.)

Does make upgrade fetch head?

Thanks

Nik
