Switching asterisk versions

Hi.
I’ve been working on setting up a new server for my company. i had to start with version 3.x because of what we currently use so i could transfer the backup files. Everything has gone well so far and i’m now running version 6.12.x One thing i’ve been wanting to do is switch to a newer asterisk version. At first i was running asterisk 10 and i successfully managed to upgrade to 11 using the following command.
asterisk-version-switch
According to the documentation i found i should be able to switch to 13 using the same command, however that isn’t an option in the script.
Do i have an out of date script? If so, where can i find an updated one?

Thanks.

You need to update your distro.

Hi.
Just to be clear in my mind, are you talking about my operating system like sendOS when you say i have to upgrade my distro?

Thanks.

No.

Hi.
Thanks for the help.
That’s what i needed.
Part of the issue was that this is the first time for me building a freepbx system and because of existing structure i was forced to start with what the company had. i had to start on distro version 3.211.6310 so as you can guess, that’s a lot of updates!!
O well, they are all complete now so no worries.
As a side note, what’s the best way to get notified of new stable releases?
