General NFM-P upgrade pathway

Description

Use this pathway through the documentation to access detailed procedures for upgrading an NFM-P system.

Note: The pathway applies to an upgrade in a staging environment or in a live network.

Stages
Pre-upgrade
 
1 

Perform To prepare for an NFM-P system upgrade to collect the required information and to ensure that the correct upgrade conditions are in place.

2 

If SELinux is enabled in the NFM-P, and you want SELinux enabled after the upgrade, perform To prepare an SELinux-enabled NFM-P system for an upgrade to ensure that SELinux is enabled and in permissive mode before the upgrade.

Upgrade
 
3 

Perform one of the following.

  1. Upgrade a standalone NFM-P system; see Standalone NFM-P system upgrade.

  2. Upgrade a redundant NFM-P system; see Redundant NFM-P system upgrade.

Post-upgrade
 
4 

If either of the following is true, perform “How do I enable SELinux enforcing mode for the NFM-P?” in the NSP System Administrator Guide to switch from SELinux permissive mode to enforcing mode.

  • You have performed To prepare an SELinux-enabled NFM-P system for an upgrade to set SELinux in permissive mode before the upgrade, and want to restore the use of enforcing mode.

  • The upgrade has enabled SELinux in the NFM-P for the first time, but in permissive mode, and you want the more stringent security of enforcing mode.
