Prepare to Change the Performance Center Version

The NFA console or stand-alone server must be registered as a data source for a supported version of CA Performance Center (CA PC) or CA NetQoS Performance Center (NPC). If you plan to to switch between NPC and CA PC, prepare for the switch as described in this topic:

1. Prepare for unregistering from your current Performance Center version as described below.
2. Unregister from Performance Center
3. Perform the CA Network Flow Analysis upgrade.

Important! We generally do not recommend unregistering. 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 upgrade CA Performance Center to version 2.3.3, upgrade CA Network Flow Analysis first.
• If you plan to switch between types of Performance Center, unregister before you upgrade CA Network Flow Analysis. For example, unregister before you switch from CA NetQoS Performance Center to CA Performance Center or you switch from CA Performance Center to CA NetQoS Performance Center.

Results of Unregistering from CA NetQoS Performance Center

If you unregister CA Network Flow Analysis from CA NetQoS Performance Center and register again with CA Performance Center, 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 CA NetQoS Performance Center 6.1.205 SP2/6.1.194 are retained with no changes in their status.
• Single Sign-On (SSO) customizations: LDAP and other SSO customizations are retained.

  If you change to a new SSO version, update the SSO configuration settings as described in the Single Sign-On User Guide.

Follow these steps:

1. Log in to the Console for CA NetQoS Performance Center as a user who is a member of the Administrators group.
2. Review your records of the customizations in CA NetQoS 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. (Optional) Prepare for the effects of unregistering:

   Consider giving a unique name to each group so it is easy to restore the group hierarchy. For example, name each group in a way that indicates its relationship to other groups.

   To ensure that no groups are deleted, flatten the group hierarchy before you unregister.

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