Migration considerations
Migrating IBM® Capacity Management Analytics involves upgrading software components and deploying new Capacity Management Analytics report content.
Due to the software components changing and the changes to the underlying architecture, it is recommended that a new Capacity Management Analytics installation be made regardless of the prior version. However, if TDSz Version 1.8.2 is already in use then no migration needs to be performed for Capacity Management Analytics. If you wish to keep the same database and schema names from the prior Capacity Management Analytics datastore, then the old one will need to be purged before doing so.
The prior version of Capacity Management Analytics can exist in parallel with the new installation as long as the new Capacity Management Analytics database is not sharing the prior database and schema names and TDSz is Version 1.8.2. It is recommended that you install and validate the new Capacity Management Analytics installation before removing the prior version.
When you migrate, install the new software and deploy the report content to a test environment where you can verify the report outputs. Then, after you are satisfied that the new product is working as expected, you can migrate your production environment.
When you migrate from an existing version, all of the report content that is deployed to IBM Cognos® Analytics is overwritten. If you created new reports or modified any reports in the Capacity Management Analytics Solution Kit, you must take extra steps to preserve your new or modified reports.
IBM Cognos Analytics reports
In IBM Cognos Business Intelligence, you should back up your new and modified reports before you deploy Capacity Management Analytics 2.1.1. You can redeploy the reports, but you should do so to a new location in IBM Cognos Business Intelligence.
For more information about upgrading or migrating IBM Cognos BI, see the upgrading documentation on IBM Knowledge Center (www.ibm.com/support/knowledgecenter/SSEP7J_10.2.2/com.ibm.swg.ba.cognos.inst_cr_winux.10.2.2.doc/c_upgradingtocognos8.html%23UpgradingtoCognos8)
Framework Manager models
Also, if you modified the IBM Cognos Framework Manager models, you must apply your modifications to the Capacity Management Analytics 2.1.1 version of the models.
If you want to continue to use the previous version of the model, you should rename the models and store them in a new location. You must also remap the reports in IBM Cognos Business Intelligence to use the previous version package as the path will have changed.
Report templates
If you want to keep the previous version report templates, you can copy the entire template folder into Capacity Management Analytics 2.1.1, but ensure that you use a new name for the folder in IBM Cognos Business Intelligence. Additionally, you must remap objects as the path will have changed due to the new name.
To migrate any report objects that you created, you should rename the model, report, template, or workspace folders in the previous version before you copy them to the new version.
SPSS Modeler streams
If you have created any IBM SPSS® Modeler streams in your previous version, you will have to modify the streams to use in the new version as the database tables and column names have changed. Also, if you have modified any streams, the table and column names have changed in the new version, so you must manually update any streams that you have modified.
Capacity Management Analytics database
Before you migrate your Capacity Management Analytics ensure that you back up your Capacity Management Analytics database. Specifically, ensure that you back up all tables that have HCM as the prefix and all of the tablespaces that have IDHTS as the prefix.
If you use any Capacity Management Analytics database tables as source data for any applications, you must change the names in the new version as the table names will have changed.
Tivoli Decision Support for z/OS database
It is also recommended that you back up the Tivoli® Decision Support for z/OS® database. For more information, see IBM Knowledge Center (www.ibm.com/support/knowledgecenter/SSH53X_1.8.2/com.ibm.tivoli.dszos.doc.1.8.2/Admin/abackup.dita).
