Plan the Upgrade or Migration

The path that you take for your upgrade or migration depends on various factors.
The path that you take to upgrade or migrate depends on various factors. Use the following sections to plan your upgrade or migration:
Upgrade Paths
You can upgrade directly to this version from
DX NetOps Performance Management
3.7 or 20.2. To upgrade from an earlier version, first upgrade to
DX NetOps Performance Management
3.7 or to 21.2.2 or lower, and
then
upgrade to this release.
Upgrade Scenarios
To plan your operating system (OS) upgrade and understand the upgrade scenarios, review the following graphic. This graphic provides a high-level overview of some common OS upgrade scenarios. Use this graphic to identify your upgrade scenario, and then use the procedures that are outlined in the following sections:
Plan_Upgrade
Plan_Upgrade
If you are set up
DX NetOps Performance Management
in a cloud environment, see Rehydrate Data in a Cloud Environment.
The OS upgrade scenarios upgrade the OS for all components. However, your unique scenario might upgrade or install the OS for a select set of components.
Upgrade without an Operating System Upgrade
If this version of
DX NetOps Performance Management
supports your current OS, you can upgrade each component using its supported upgrade path.
For more information about the OS that
DX NetOps Performance Management
supports, see Upgrade Requirements and Considerations.
Upgrade with a Minor OS Upgrade
If you are performing a minor OS upgrade (for example, you are upgrading from Red Hat Enterprise Linux (RHEL) 6.6 to RHEL 6.9), do the following tasks:
DX NetOps Performance Management
is upgraded with a minor OS upgrade.
Migrate
Migration involves moving the
DX NetOps Performance Management
components—including configurations, customizations, and data—from one system to another system.
The following situations require that you migrate:
  • You are moving to new hosts for an OS install (for example, from RHEL 6.9 to RHEL 8.1 or SUSE Linux Enterprise Server (SLES) 12 SP2).
  • The current database hardware no longer meets the sizing requirements.
  • You are moving from virtual machines to physical hardware for the database.
Migrate to New Hosts from a Supported Operating System
Use the following process if you are moving
DX NetOps Performance Management
components to new systems with new IP addresses and hostnames from a supported OS:
  1. Upgrade the components using their supported upgrade path.
    Upgrade the existing system to the
    DX NetOps Performance Management
    version to which you are migrating
    before
    migrating.
  2. Migrate the components in the following order:
    1. Migrate the data repository.
      Depending on the amount of data, migrating the data repository can take a significant amount of time.
      To minimize downtime, perform incremental backups after your initial backup.
    2. Migrate
      NetOps Portal
      .
      This migration procedure copies over
      NetOps Portal
      and does not require you to install
      NetOps Portal
      on the new host.
The
DX NetOps Performance Management
components are migrated to new hosts from a supported OS.
Migrate to New Hosts from an Unsupported Operating System
Use the following process to moving
DX NetOps Performance Management
components to new systems with new IP addresses and hostnames from an unsupported OS:
  1. Back up the components to another server in the following order:
    1. Back up the data repository.
      Depending on the amount of data, backing up and restoring the data repository can take a significant amount of time.
      To minimize downtime, perform incremental backups after your initial backup.
  2. Install the OS on each host.
  3. Restore the components in the following order:
    For each component, verify that the backup is copied over.
  4. Migrate the components in the following order:
    1. Migrate the data repository.
      Depending on the amount of data, migrating the data repository can take a significant amount of time.
      To minimize downtime, perform incremental backups after your initial backup.
    2. Migrate
      NetOps Portal
      .
      Migrating
      NetOps Portal
      copies over
      NetOps Portal
      and does not require you to install
      NetOps Portal
      on the new host.
The
DX NetOps Performance Management
components are migrated to new hosts from an unsupported OS.
Install on an Operating System from a Supported Operating System
Use the following process if you are performing a major OS upgrade from a supported OS (for example, from RHEL 6.9 to RHEL 7.5 or SLES 12 SP2) on the same systems with the same IP addresses and hostnames:
  1. Upgrade each component using its supported upgrade path.
    Upgrade the existing system to the product version to which you are backing up and restoring
    before
    backing up and restoring.
  2. Back up the components to another server in the following order:
    1. Back up the data repository.
      Depending on the amount of data, backing up and restoring the data repository can take a significant amount of time.
      To minimize downtime, perform incremental backups after your initial backup.
  3. Install the OS on each host.
  4. Restore the components in the following order:
    For each component, verify that the backup is copied over.
DX NetOps Performance Management
is installed on an OS from a supported OS.
Install on an Operating System from an Unsupported Operating System
Use the following process if you are performing a major OS upgrade from an unsupported OS (for example, RHEL 6.9) on the same systems with the same IP addresses and hostnames:
Prerequisite:
(If your current OS is RHEL 5.x) You have moved to a version that
DX NetOps Performance Management
supports.
For more information about the OS that
DX NetOps Performance Management
supports, see Upgrade Requirements and Considerations.
