You can check the current installed version using the following command
<code>
yum info fastdpi
</code>

 
Downgrade to 9.1:

<code>
yum downgrade fastdpi-9.1 fastpcrf-9.1 fastradius-9.1
</code>

After the version is changed, a service restart is required:

<code>
service fastdpi restart
</code>

:!: If PCRF and/or Radius are used, they also require restart


:!: Do not upgrade the Linux kernel. In newer versions of the kernel binary compatibility with Kernel ABI may be broken and the network driver will not boot after the update. If you did update, then temporarily (during solving the problem) configure the grub boot loader to load the previous kernel version (in the /etc/grub.conf file please set the following option: default = 1).

If there is a warning that the update is not found or problems with dependencies are found, then run the command before updating:
<code>
yum clean all
</code>
