Key considerations for migration

Before migrating from TrueSight Capacity Optimization to BMC Helix Continuous Optimization, consider the factors listed in this topic.

Make sure that TrueSight Capacity Optimization is upgraded to version 20.02. To migrate data from a version earlier than 20.02, you must first upgrade to 20.02 and then migrate data to BMC Helix Continuous Optimization. For more information, see TrueSight Capacity Optimization 20.02.

Data that you can migrate

When you run the migration tool, the following data is migrated automatically:

Analyses and models
Basic reports, basic report templates, and report results
Catalog entities
Custom metric profiles
Entity filters and time filters
ETL tasks and custom ETL code
Events
Historical data
Relations
Tags and tagging rules
SQL and Summary Data marts
Custom Optimizer rules
Statistics (Min, Max, AVG)
Custom statistics (migrated as Baselines)
View groups and custom views with the supported templates. For details about the templates that are not supported, see Features that are not supported in BMC Helix Continuous Optimization.
Derived entities

What's changed for some of the features?

The following table lists the features or tasks that have different UI or behavior after migration.

TrueSight Capacity Optimization 20.02	BMC Helix Continuous Optimization
Data marts	All the data marts are migrated. To find the status of the data marts, navigate to Administration > Data marts. Filter on the Status column to view the status of the migrated data marts. Summary data marts with Database Server entity type must be changed to use Entity filter created using tags. For the data marts that show the status as Error or Warning, you may need to re-create the SQL data marts by using the Summary data mart wizard in BMC Helix Continuous Optimization. For more information, see Creating-a-summary-data-mart-for-a-custom-view and Managing-entity-filters. If you do not want to migrate the data marts and views, update the value of the migrate-datamarts-and-views parameter to false in the application.properties file. For more information, see Running-the-migration-tool.
Gateway Server	Although Gateway Server is supported in BMC Helix Continuous Optimization, it will not be migrated. You can configure the Gateway Servers after migration.
Virtual node	BMC Helix Continuous Optimization does not contain the Virtual Node system type for data imported from an operating system. BMC Helix Continuous Optimization provides separate namespaces for each metric that is imported from hypervisors and operating systems. After migration, metrics from the Virtual Node system type are assigned the opt:meas:vn namespace. For more information, see Namespaces.
Optimizer rules	Optimizer rules based on out-of-the-box templates are not migrated. If you have done any customizations to these rules in TruSight Capacity Optimization, you must add them manually post-migration. SNMP configuration is not supported in Optimizer rules. Optimizer thresholds are not migrated to BMC Helix Continuous Optimization. The default optimizer system tasks are not migrated to BMC Helix Continuous Optimization. Optimizer rules that were configured with user-defined optimizer system task are migrated to the optimizer-daily system task. Formula condition type: A new advanced option, Scaling of percentage values, is introduced for migrated rules. By default, the property is set to 0 - 1 (compatibility with 20.02 formulas) option to perform the required scaling for percentage metrics for the migrated rules. Optimizer rules based on data marts: Data marts based on Analysis or Model execution are not migrated. Rules that are based on such data marts must be modified manually. The filters section is not available in data marts. If the data mart was configured manually by using the Data marts > View selection type > manually specified option, the rule is not migrated. Custom Optimizer rules based on System type filters must be changed to use the Entity filter option instead.
Custom optimizer rules > Monitor violation	Renamed as Good/Warn/Poor Samples Count.
Custom optimizer rules > Data vs. Statistic	Renamed as Data vs. Baseline. Details resolution is not supported in Data vs. Baseline condition type. After migration, the rule that was configured with Details resolution will be available as Hourly resolution. Data vs Baseline – Baseline section uses the same resolution as the condition. Baseline of other resolutions are not supported. Rule-based custom statistics that were defined in Administration > Data Warehouse > Custom statistics in TrueSight Capacity Optimization are available as Baselines in BMC Helix Continuous Optimization. For details, see Support for custom statistics.
Custom optimizer rules > Statistic vs. Threshold	Renamed as Data vs. Threshold. Day resolution is available as Summary resolution in BMC Helix Continuous Optimization.
Custom statistics	Rule-based custom statistics that were defined in Administration > Data Warehouse > Custom statistics in TrueSight Capacity Optimization are now available as Baselines in BMC Helix Continuous Optimization. Producer-based and Rolling statistics are not available as is in BMC Helix Continuous Optimization
Custom statistics > Rule-based custom statistics > Type as Percentile	Custom statistics of Percentile type will be available in the Aggregation list in Baselines as a fixed set of percentile values. Percentile that are not available in the Aggregation list, for example, 85th percentile (any user-defined percentile) will be mapped to the nearest fixed percentile value, that is 95th percentile for 85th percentile after the migration.
Custom statistics >Rule-based custom statistics > Aggregation	The following aggregation values are not available. Weighted average Duration Weighted average Expected sum Count Percentile values are available in the Aggregation list.
Custom statistics > Rule-based custom statistics > Aggregation groups	The The same day class option is not available. Other options are available in the Consider data for property.
Custom statistics > Rule-based custom statistics > Input resolution	Not available. The baseline uses the resolution as selected in the analysis editor or in condition type as Data vs. Baseline of the custom optimizer rule.
Custom statistics > Rule-based custom statistics > Output	Not available
Custom statistics > Rule-based custom statistics > Input statistic	Not available
Administration > ETL & System tasks	If there are Database Server entity types extracted by Oracle - Enterprise Management ETL before migration, Oracle - Enterprise Management ETL must be executed soon after migration and manually reconcile the resulting entities of Generic entity type with their Virtual Machine counterparts extracted by vCenter ETLs or VIS file parser ETLs.

Features that are not supported in BMC Helix Continuous Optimization

BMC Helix Continuous Optimization includes changes to the level of support for the following features that are currently supported in TrueSight Capacity Optimization:

Features planned for future releases
