Upgrade and Downgrade Support Policy for Junos OS Evolved Releases

We have two types of releases, Standard EOL and EEOL:

  • End of Life (EOL) releases have engineering support for twenty four months after the first general availability date and customer support for an additional six more months.

  • Extended End of Life (EEOL) releases have engineering support for thirty six months after the first general availability date and customer support for an additional six more months.

For both Standard EOL and EEOL releases, you can upgrade to the next three subsequent releases or downgrade to the previous three releases. For example, you can upgrade from 21.4 to the next three releases – 22.1, 22.2 and 22.3 or downgrade to the previous three releases – 21.3, 21.2 and 21.1.

For EEOL releases only, you have an additional option - you can upgrade directly from one EEOL release to the next two subsequent EEOL releases, even if the target release is beyond the next three releases. Likewise, you can downgrade directly from one EEOL release to the previous two EEOL releases, even if the target release is beyond the previous three releases. For example, 21.4 is an EEOL release. Hence, you can upgrade from 21.4 to the next two EEOL releases – 22.2 and 22.4 or downgrade to the previous two EEOL releases – 21.2 and 20.4.
