Hi, have you read this page?
That update script will upgrade FreePBX Distro from 3.211.63-10 to 4.211.64-1 as per Wiki page (then you can apply in strict sequence all remaining update script for the 4.211.64 branch…but this is another story).
You should first try to understand which version is now running your FreePBX Distro by using these commands as Linux’s root:
cat /etc/asterisk/freepbxdistro-version
or, eventually, this one:
cat /etc/schmooze/pbx-version
and then you can plan an upgrade from FreePBX Distro 3.211 to 4.211 (passing from CentOS 6.3 to 6.4).
I think you should:
(1) verifying what version your system is running now as stated above.
(2) use the NEW update script as per Wiki page I linked above.
I think (and it was reported at end of July on this same Forum, read this post) that you’re using (or you used) the OLD upgrade script which was probably a little bit buggy (as far as I understood the whole story).
Running the upgrade script via command line did the trick. I was running version 3.211.63-10, and am now at 4.211.64-1. I’ll run the rest of the 4 series updates in sequence.
As Preston wrote you can use now SysAdmin Pro (I have it too) or you can make some basic practice with the CLI (which could be always useful): a little bit annoying tasks in comparison to use the GUI but always nice to know how to do.
