Upgrade to CentOS 7

CentOS 6 is End Of Life and yum updates are broken: How to enable CentOS 6 Vault or Upgrade to CentOS 7


If you are having problems updating your CentOS 6 installation this is because CentOS 6 is End Of Life and the official repositories have been archived.

The problem looks something like this:

# scopserv_yum update
==== scopserv_yum ====
— Executing yum…
Loaded plugins: fastestmirror
Setting up Update Process
Determining fastest mirrors
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
 Eg. Invalid release/repo/arch combination/
removing mirrorlist with no valid mirrors: /var/cache/yum/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base
— Done

You can enable the CentOS6 Vault with the following command.

rpm -Uvh https://download.scopserv.com/dist6/packages/scopserv-server//scopserv-server-6.21.0.0.20210201-1.nodist.scopserv.noarch.rpm

But this is not a long term solution and ScopServ recommends you upgrade to CentOS 7 at least until CentOS 8 Stream is supported.

The upgrade process is to backup your existing configuration, install a clean copy of CentOS 7 with our official CentOS 7 ISO and then restore your configuration.

Follow this documentation to Backup your server:

The WinSCP method is the preferred method.

Install using the official ScopTEL CentOS 7 ISO


After completing the ISO installation, follow the Restore procedure to Restore your Backup.
