Preparing Windows Servers › Unregister from CA Performance Center

Unregister from CA Performance Center

The NFA console or standalone server must be registered as a data source with a supported version of CA Performance Center or CA NetQoS Performance Center. Your next step depends on your current software version and the version you want to use after the upgrade, as described in the following table.

Many customizations are lost when you unregister and register again. Read this topic carefully to prepare for these events.

General Guidelines:

• If you need to unregister, complete the steps in this topic before you start the CA Network Flow Analysis upgrade.
• Upgrade CA Network Flow Analysis first if you need to upgrade the following software:
  • CA NetQoS Performance Center from 6.1.x to 6.1.194
  • CA Performance Center 2.1.x to CA Performance Center 2.2.x, then optionally to version 2.3.x
  • CA Performance Center 2.2.x to CA Performance Center 2.3.x

You can upgrade to CA Performance Center 2.2.x or 2.3.x incrementally from version 2.1.x, but you cannot upgrade to version 2.2.x or 2.3.x from 2.0.x or an earlier version.

We generally do not recommend unregistering. We recommend that you unregister only when you cannot upgrade to the CA Performance Center version that you want to use.

Results of Unregistering:

If you unregister CA Network Flow Analysis from CA Performance Center 2.0.x or CA NetQoS Performance Center 6.1 and register it again with CA Performance Center 2.2.x or 2.3.x, the following rules apply:

• Domains:
  • The default domain is retained. Groups, users, devices (routers), interfaces, protocol names, and ToS labels that are assigned to the default domain retain their assignments.
  • Custom domains are deleted.
  • Groups, users, devices (routers), and interfaces in custom domains are reassigned to the default domain.
  • Protocol names, ToS labels, AS names, and IP addresses in custom domains become inaccessible.
• User accounts:
  • User accounts are retained if the users have valid product privilege settings (User, Power User, or Administrator) for CA Network Flow Analysis. User accounts with no product privilege for CA Network Flow Analysis are deleted.
  • User accounts that are associated with custom domains will be associated with the default domain instead.
  • If the user account 'nqadmin' exists and has a product privilege that is lower than Administrator, this user account acquires the Administrator product privilege.

  You cannot add new users or edit user account settings after you unregister.

• Roles:
  • Custom and default roles are retained and continue to be associated with user accounts.
• Groups: Retained if the following conditions are met:
  • The group is a default group in CA NetQoS Performance Center or is a group that was pushed up to CA NetQoS Performance Center. 'Dynamic groups,' for example, cross-product groups, are deleted.
  • The group has contents--that is, the group is not empty.

  Custom and default groups require cleanup on the Manage Groups page in CA Performance Center after you unregister and register with the newer software. The following changes may occur:

  • Some group names change slightly. For example, the group 'All Interfaces' is renamed 'Interfaces.'
  • Structures may flatten so that a group that was nested under another group is not nested.
  • Groups may be relocated:

    A custom group that originally was shown on the Manage Groups page under All Groups/System Groups/Data Sources/ReporterAnalyzer is under Network Flow Analysis in the new group tree. The new location is All Groups/Inventory/Data Sources/Network Flow Analysis.

    If the custom group originally was not under ReporterAnalyzer, it is moved to sit under Network Flow Analysis.

  • Duplicate groups may be created.
  • Empty custom groups are deleted.
• SNMP profiles: SNMP profiles from NetQos Performance Center 6.1.194 are retained with no changes in their status.
• Single Sign-On (SSO) customizations: LDAP and other SSO customizations are retained.

  Note: If you upgrade from CA NetQoS ReporterAnalyzer 9.0.1, you also will change to a new SSO version. Update any previous SSO LDAP configuration and check other SSO customizations. Options from the previous SSO version may not match the current options or may not comprise a full set of the current options. For information about configuring SSO, see the Single Sign-On User Guide.

Follow these steps:

1. Log in as a user who is a member of the Administrators group.
2. Review your records of the customizations in CA NetQoS Performance Center or CA Performance Center, such as:
   • User accounts and their roles, product permissions, groups, and domain access
   • Custom roles and standard roles that have been customized, including any assignments for top-level menus, dashboards, and dashboard menus
   • Group structure and naming conventions
   • Custom domains and their contents, such as groups, devices, interfaces, SNMP profiles, report folders, AS names, protocol names, ToS labels, and IP addresses

   Remember that these elements may require checking, restructuring, or restoration.

3. Open the Data Source List: Click Admin, NetQoS Settings group, Data Sources.
4. Select the Reporter Analyzer or CA Network Flow Analysis data source.
5. Click Delete.
