Currently: Asterisk 1.4
Goal: Asterisk 1.6
This scenario is more of a learning experience for me since I'm a junior Linux admin. We can't use virtual machines. Only 1 physical test machine. Why? They didn't really say....
Anyway, it seems that Asterisk version 1.4 has some kind of memory leak quirk which causes us to have to restart the Asterisk service every day on the production machine. If we don't restart it then eventually calls stop. The powers that be came up with a solution to migrate to Asterisk 1.6 because it seems that the problem was corrected in that version. They decided it would be best to do the following:
Run Asterisk 1.4 AND 1.6 on a test server. Import the production server's configs into both installs. Test that both installs work. Run the 1.6 version for a bit to make sure there are no issues. Then migrate to version 1.6 on the production server. In order to get the test system up and running on version 1.4 the following was done:
1. Setup a test box with Cent O/S.
2. Install Asterisk 1.4
3. Make a backup copy of /etc/asterisk called /etc/asterisk.orig
4. Copy all files from /etc/asterisk on production server into test server into /etc/asterisk directory
5. On test server make a backup copy of /var/lib/asterisk called /var/lib/asterisk.orig
6. Copy all files from /var/lib/asterisk on production server into /var/lib/asterisk
7. Import a copy of the production server's MySQL database
All the above went correctly, and Asterisk 1.4 is running fine. I'm at the point where I want to install version 1.6 but I don't want to install it in the same directory as 1.4 and overwrite it.
1. How can I control where it will install Asterisk 1.6?
2. Could I "toggle" between 1.4 and 1.6?
And more importantly...
3. Is it even possible to run both versions on the same box?
