Migrating Spectrum legacy landscapes to huge landscapes

Products

• Spectrum
• Network Observability

Issue/Introduction

Our current Spectrum installation is using legacy landscapes. We need to migrate these landscapes to use huge landscapes to take advantage of the number of models per landscape.

Environment

Release: Any
Component: Modeling Gateway

Resolution

The Modeling Gateway supports exporting topology information and configuration settings from a SpectroSERVER. The information is exported into an XML-formatted file, which can then be imported into a specified SpectroSERVER using the Modeling Gateway.

The following types of information are exported by default:

• Device elements, with configuration attributes.
• Port elements, with configuration attributes.
• Container elements, with configuration attributes.
• Connections (resolved and unresolved, WA_Link connections).
• Universe topology hierarchy.
• Layout for each view in the Universe topology, including annotations and zoom information but excluding background images.
• User models and the entire user scheme such as user-related relations, attributes, and models like LicenseRole, AccessGroup, PrivilegeRole, and UserGroup.
• Discovery configurations.
• Service Management schemes and attributes.
• Static and dynamic global collections including all the models in each global collection, all dynamic collection criteria, zoomed list, grouped list, and topology layout.
• Use the Modeling Gateway (MGW) to export the database from the legacy landscape and then import the database to the huge landscape.

NOTE: Examples of types of data which are not exported includes but are not limited to:

• Service Performance Manager (SPM) tests
• NCM configurations
• Events.

Export the legacy database:

• Log into the legacy landscape system as the user that owns the Spectrum installation
• cd to the $SPECROOT/SS directory
• Enter the following command to export the legacy database using the MGW where <VNM> is the hostname of the legacy landscape system and <FILENAME> is the filename to save the exported database:

../SS-Tools/modelinggateway -vnm <VNM> -e <FILENAME>

For example:

../SS-Tools/modelinggateway -vnm MyLegacyLH -e MyLegacyLH

NOTE: The MGW export file append ".xml" to the export file. In the above example, the export file would be "MyLegacyLH.xml".

Import to huge legacy:

• Install Spectrum on the new system specifying huge landscape
• Log into the system as the user that owns the Spectrum installation
• Start the SpectroSERVER process
• Copy the MGW export file from the legacy landscape system into the $SPECROOT/SS directory on the huge landscape system
• cd to the $SPECROOT/SS directory
• Enter the following command where <VNM> is the hostname of the huge landscape system and <FILENAME> is the filename of the MGW export file from the legacy landscape system:

../SS-Tools/modelinggateway -vnm <VNM> -i <FILENAME>

For example:

../SS-Tools/modelinggateway -vnm MyHugeLH -e MyLegacyLH.xml
