[asterisk-users] Upgrade from 1.0.x to AsteriskNOW 3.0

[Andre Goree]

Hello all.  I was hoping someone out there might have some advice or 
suggestions regarding an upgrade from an archaic Asterisk version.

I've been given the daunting task of upgrading a very old Asterisk-1.0.x 
install to a recent LTS version.  I'll also need the install to have 
high-availability and failover support.

 From my research, it would appear that AsteriskNOW-3.0 might be my best 
bet, as it seems to be running Asterisk-11.  I've previously installed 
Asterisk-11+FreePBX in a VM, and this appears to be very similar.  Is 
there any upside to using AsteriskNOW vs. Asterisk+FreePBX? Other than 
the obvious fact that everything is nicely placed on an iso for ease of 
installation?

As for the actual upgrade, is it possible to step through each of the 
UPGRADE*.txt files under the Asterisk-11 source?  I.e, UPGRADE-1.2.txt 
-> UPGRADE-1.4.txt -> UPGRADE-1.6.txt -> UPGRADE-1.8.txt -> UPGRADE.txt? 
Or would it be prudent to recreate my current 1.0.x configuration under 
Asterisk-11 instead?

Regarding HA/failover, is a hardware solution (such as Digium's 
R800/R850) my only option?  During my research I've found scripts on the 
internet that allow for failover using arp/nmap, however those appear to 
only work for hardware failures.  I would need something that can 
account for both hardware and software failures.

Thanks in advance for any advice that anyone can give on the subject.  
Any suggestions, etc. would help immensely!
