[Asterisk-Users] Upgrading Asterisk

[Martin Roy]

I'm about to upgrade my currently running asterisk server from 1.0.3 to 
1.0.6 is there anything I should do before doing the upgrade?

I know since I'm using Fedora Core 3 that I must do for Zaptel : make 
clean then make linux26 and finally make install.

Do I have to remove the version 1.0.3 first or only doing install will 
replace all existing modules without removing my config files?

Once I have installed Zaptel 1.0.6 then do I have to do something 
special to upgrade asterisk from 1.0.3 to 1.0.6?

As I have a lot of people using the asterisk server I can't put it down 
for a long time so I want to be sure I don't make any stupid mistake 
before doing the upgrade as I don't have time to reinstall everything 
from scratch if something goes bad.

Thanks

Martin
