Key considerations for migration

Consider the following factors before migrating from TrueSight Capacity Optimization to BMC Helix Continuous Optimization.

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
Optimizer rules
Relations
Tags and tagging rules
SQL and Summary Data marts
View groups and custom views with the supported templates. For details about the templates that are not supported, see the following section.

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

Some features will be available in future releases of BMC Helix Continuous Optimization:

Reservations
Investigate
Capacity views - AIX, Hyper-V, Datacenter Overview, Hadoop, Network, OpenStack, Solaris, XenServer
Sunburst custom view templates

For more information about these features, see TrueSight Capacity Optimization 20.02.

Important

All of the future product plans and releases described herein relate to the current BMC product development considerations, which are at the sole discretion of BMC and are subject to change and/or cancellation at any time. BMC cannot provide any assurance as to whether these plans will result in any future releases of the nature described.

Discontinued features

Support for some features, such as Integration Studio, Virtual Planner, and Chargeback is discontinued in BMC Helix Continuous Optimization. For a complete list of the discontinued features, see Deprecated-and-discontinued-features.

Note: If you are using self-ETLs in TrueSight Capacity Optimization, you can use formula or custom ETLs to compute those custom metrics.

Support for data marts, Gateway Server, and virtual nodes

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. 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.

Although Gateway Server is supported in BMC Helix Continuous Optimization, it will not be migrated. You can configure the Gateway Servers after migration.
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.

Support for optimizer rules

The following table lists the UI label changes for the condition types in the optimizer rules.

TrueSight Capacity Optimization 20.02	BMC Helix Continuous Optimization 22.3	Notes
Monitor violation	Good/Warn/Poor Samples Count
Data vs. Statistic	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. The following aggregation that were available in Administration > Data Warehouse > Custom statistics section are not available. Weighted average Duration Weighted average Expected sum Count Custom statistics that were defined in Administration > Data Warehouse > Custom statistics in TrueSight Capacity Optimization are not available as is in BMC Helix Continuous Optimization. Instead, the custom statistics of Percentile type will be available in the Aggregation function list in the Data vs. Baseline condition type. Percentile that are not defined in the Aggregation function, for example, 23rd percentile (any user-defined percentile) will be available as 95th percentile after the migration.
Statistic vs. Threshold	Data vs. Threshold	In the Data vs. Threshold condition type, Day resolution is available as Summary resolution in BMC Helix Continuous Optimization.
Data vs. Threshold	Data vs. Threshold	No label changes.
Based on data marts	Based on data marts	No label changes.

Additional considerations

SNMP configuration is not supported in Optimizer rules.
Thresholds and optimizer system tasks are not migrated to BMC Helix Continuous Optimization. Rules that were configured with user-defined optimizer system task, will be 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.
- Filters section is not available in data marts.
- If the data mart was configured manually using the Data marts > View selection type > manually specified option, the rule will not be migrated.

Functions managed by BMC

The following administration functions related to components in your on-premises environment are not available in BMC Helix Continuous Optimization because they are now managed by BMC.

Global configuration tasks that include SNMP notifications, search options, and manual editing of system properties
Maintenance tasks that include configuring logs and software updates
Modification of the data warehouse aging properties
Primary scheduler restart
