# End-of-Life Announcement

NIOS 8.6.x will reach its end-of-life (EoL) in April 2025. Infoblox recommends that you upgrade to NIOS 9.x to ensure continued support and coverage.

# 8.*x* to 9.0.*x* Upgrade Paths

Infoblox recommends that you upgrade to NIOS 9.0.*x* from these tested and validated releases:

8.6.4, 8.6.3, 8.6.2, 8.5.5, 8.5.2, and 8.4.8

# Unsupported Upgrade Paths 

- There is no direct upgrade path from NIOS 8.6.5 to NIOS 9.x until the release of NIOS 9.0.7 (expected to release mid-2025). Customers should remain on their existing NIOS 8.4.x or 8.5.x or 8.6.x versions and plan to upgrade directly to NIOS 9.*x* before April 30, 2025, to ensure continuous support. Infoblox recommends that most customers upgrade directly to NIOS 9.x and do not upgrade to NIOS 8.6.5.
- You cannot upgrade to NIOS 9.0.*x* from NIOS 8.3.*x* and earlier releases.

# Critical Upgrade Information

- Ensure that the latest consolidated hotfix (CHF) for your current 8.*x* release has been activated and applied before upgrading to 9.0.*x*. For example, if you want to upgrade from 8.6.3 to 9.0.6, ensure that have applied the NIOS 8.6.3.5 consolidated hotfix before upgrading to 9.0.6.   
The following is a list of consolidated hotfixes that have been released for NIOS 8.*x*:
  - NIOS 8.6.3.5
  - NIOS 8.6.2.4
- If you are upgrading to 9.x from a version lower than 9.0.0, apply the NIOS-98022 hotfix before the upgrade.
