1 Introduction

1.1 Overview

Oracle's Cloud Native Core (CNC) Network Functions (NFs) support deployment on Oracle Communications Cloud Native Environment (CNE), non-Oracle cloud native environment, and Oracle Cloud Infrastructure (OCI) environment. This document provides information on Cloud Native Core (CNC) guidelines required to upgrade and rollback Oracle CNC Solution in the following environment:

• CNC Solution deployed on CNE: For information on upgrade or rollback procedures, see Upgrade of Oracle CNC Solution deployed on Oracle CNE.
• CNC Solution deployed on non-Oracle CNE: For information on upgrade or rollback procedures, see Upgrade of Oracle CNC Solution deployed on Non-Oracle CNE.
• CNC Solution deployed on OCI: For information on upgrade or rollback procedures, see Upgrade of Oracle CNC Solution deployed on with OCI.

Oracle CNC Solution includes:

• when deployed on Oracle CNE:
  • CNC NFs
  • CNC Companion Components
  • CNE
• when deployed on non-Oracle CNE:
  • CNC NFs
  • CNC Companion Components

CNC NF includes:

• Oracle Communications Cloud Native Core, Binding Support Function (BSF)
• Oracle Communications Cloud Native Core, Converged Policy (Policy)
• Oracle Communications Cloud Native Core, Service Communication Proxy (SCP)
• Oracle Communications Cloud Native Core, Security Edge Protection Proxy (SEPP)
• Oracle Communications Cloud Native Core, Network Exposure Function (NEF)
• Oracle Communications Cloud Native Core, Network Repository Function (NRF)
• Oracle Communications Cloud Native Core, Network Slice Selection Function (NSSF)
• Oracle Communications Cloud Native Core, Unified Data Repository (UDR)

CNC Companion components includes:

• Oracle Communications Cloud Native Configuration Console (CNC Console)
• Oracle Communications Cloud Native Core, cnDBTier (cnDBTier)
• Oracle Communications Operations Services Overlay (OSO)
• Oracle Communications Cloud Native Core, Certification Management (OCCM)

1.1.1 Supported Upgrade Paths for CNC Components except CNE

Figure 1-1 outlines the supported upgrade paths for different CNC components except CNE. It is not recommend to skip intermediate versions, unless explicitly mentioned.

Figure 1-1 CNC Upgrade Paths for CNC components except CNE

Note:

• This upgrade guideline is applicable to CNC components except CNE. For CNE upgrade guideline, see Figure 2-4.
• This upgrade path is an example, and it does not show future release plans.
• If the source release is A.B.1xx, upgrades must follow an incremental sequence, for example,
  1. A.B.1xx
  2. A.B.2xx
  3. A.(B+1).1xx
  Skipping intermediate versions (such as A.B.2xx) is not supported.
• Upgrading from A.B.2xx to A.(B+1).2xx is allowed.
• Be sure to select intermediate versions to maintain compatibility throughout the upgrade.
• * Policy, CNCC, or cnDBTier supports upgrades from 24.2.x to 25.1.2xx (this exception applies only to upgrade from 24.2.x to 25.1.2xx).
