On March 31, 2017, TufinOS 1.x will reach its End of Live (EOL) as CentOS 5 does. This correlation is there since TufinOS is based on CentOS. After this date, no more patches or even security related patches will be published for TufinOS 1.x. The last versions that will run on TufinOS 1.x are 16-3 and 16-4, respectively.

So it's recommended to upgrade to TufinOS 2.x before EOL of TufinOS 1.x. Tufin describes how to upgrade in their Knowledge Center. Main information given here:

  • Upgrade should be possible from TufinOS 1.22 / TOS R13-3 or above
  • If the TOS Database is smaller than 20 GB a simple backup from the old system should be made
  • There is no way to upgrade from TufinOS 1.x to TufinOS 2.x without a new installation of the system, so a new install of TufinOS 2.x is necessary
  • After having the OS installed, the same TOS version as running on the old system needs to be installed (pls. remember, the restore of a backup works only for the same build-number)
  • Then, a simple restore of the data is possible
  • After having checked that everything works, TOS should be upgraded to the latest version, too

How to find out what is running?

TufinOS: # cat /etc/redhat-release

TOS:      # tos version
