We are planning an upgrade (in fact a migration onto new virtual servers) to 9.3H01and in the process remodelling/rebalancing the entire infrastructure (9 distributed SS), primarily using Modeling Gateway.

Does anyone know is it possible to migrate SANM policies and filters from one system to another? If so then how?

I would have thought it could be done using Modeling Gateway but don’t see anything in the docs/files to cover this.

Hello John,

This can be done adding attributes to the modelling gateway resource file

As SANM definitions are attributes you can add the attributes to .modelinggatewayresource.xml.

Manually create a Policy and Filter with the same name as those on the source system where you ran the export. If you export, for example, the model_type and landscape, add following definitions to the .modelinggatewayresource.xml:

<SpectrumConfigurationExport model_type="SANMPolicy" >
</SpectrumConfigurationExport>

<SpectrumConfigurationExport model_type="SANMApp" >
</SpectrumConfigurationExport>

<SpectrumConfigurationExport model_type="SANMFilter" >
<Model_Name attribute_id="0x1006e"/>
<model_type_list attribute_id="0xd70000" />
<landscape_list attribute_id="0xd70002" />
</SpectrumConfigurationExport>

Hope this helps

I had to do something similar with a large SANM environment and wrote a script to do it through vnmsh. I keep the SANM config on its own seperate landscape now to avoid this in the future.

It's not ideal, but with the way Relations/Associations work between Models there's no easy way to tell Spectrum to create new models and partially copy the existing Relation/Association framework from and old landscape to a new landscape's models.

My steps were

1. Manually create the policies (I only had 1, but I'd script it if I had 31)
2. read the relevant attributes from the model handle of the old filter
3. create model type filter (0xd70002) with relevant attributes
4. create association Has_Filters between the policy and the created filter model handle

Relevant attributes

Hi Lute

Thanks for your reply. I am beginning to think this will be the way to do this. I'll wait and see if Kalyan has any suggestions re the MGW before I start in earnest.

Hi Kalyan

Your suggestion isn't working for me. I have created the App, Policy and Filter models on the new server using a script so they all have the same names. And when I run the modeling gateway import I get lots of error messages similar to the following

Failed to update com.aprisma.tie.parse.ModelElement SANMFilter:Filter 1601 : model was not found.
Failed to update attributes on com.aprisma.tie.parse.ModelElement SANMApp:US_Secondary_Generic_Immediate

One thing that may be an issue is that many of the filters have the same name. For instance there are 3 x "Filter 100", 10 x "Filter 1000" etc. So the filter name is not unique.

I notice also that the Apps and Policy models, which all have unique names, give a different error. The error for those is "Failed to update attributes" whereas for the Filter models it is "model not found".

Any ideas?

John

Hi Kalyan

Do you have any further update or suggestion on this? Or do I need to go with a scripted solution?
