Summary of How legacy metric types are migrated to sections in templates
This documentation explains how legacy metric types in ServiceNow's Smart Assessment Engine application are migrated into the new assessment template structure. It details the mappings from old metric types, categories, and definitions to their corresponding sections, questions, and choices within the updated schema. This migration ensures continuity and consistency of assessment data when upgrading or implementing the Australia release version.

Metric and Category Mappings
- Metric Types: Legacy metric types are mapped to specific fields within the assessment template and context item tables—such as Name and Description fields in the
snsmartasmttemplatetable, and Table Name fields in thesnsmartasmtcontextitemtable. - Metric Categories: These are migrated to the Section table (
snsmartasmtsection), mapping fields like Name, Description, and Order to maintain structure and display order in assessment templates.
Metrics and Question Table Mappings
- Legacy metrics are mapped to the Question table (
snsmartasmtquestion) with key fields such as justification enablement, data type, guidance text, label, mandatory status, numerical limits, and order preserved. - All migrated questions default to a data type of Text. Numeric-scale metrics are assigned a Horizontal response layout for consistent user interface behavior.
- Metric types are mapped to specific question types, for example:
- Attachment metrics to Attachment questions
- Likert scales to Radio buttons
- Multiple selections to Check boxes
- Yes/No metrics to Radio buttons
Field and Definition Mappings
- Fields such as Reference and Condition in legacy tables are migrated to their corresponding fields in the Question table to maintain data integrity and filtering capabilities.
- Metric definitions are migrated to the Choice table (
snsmartasmtresponseoption), with display labels and order preserved according to the original template-definition sequence.
Assessment Template Specifics
- Only assessment templates where the Allow image field is set to false are migrated, ensuring compatibility with the new structure.
- Metrics of data type template are migrated as Radio button questions when Allow image is false at the template level.
- Assessment template definitions are migrated as choices with display text and order maintained, ensuring a seamless transition of template options.
Practical Implications for ServiceNow Customers
Customers upgrading to or using the Australia release can expect their legacy assessment metrics to be accurately mapped to the new Smart Assessment Engine schema. This migration supports continuity of assessment data and functionality without manual reconfiguration. Understanding these mappings helps IT teams anticipate how existing metrics, categories, and templates will translate into the updated system, aiding in troubleshooting and customization post-migration.
Legacy metric types are migrated to specific sections in the assessment templates in the Smart Assessment Engine application.
How metric types are mapped
This tables shows the mapping used to move the existing metric types to the section in the assessment templates.
| Existing metric type | Mapped to |
|---|---|
| Name (Translated text) (Max length 255) | Name (Translated text) field in the Assessment Template table ((sn_smart_asmt_template) ). |
| Description (Translated text) (Max length 1000) | Description (Translated html) field in the Assessment Template table ((sn_smart_asmt_template) ). |
| Table (Table Name) | Table (Table Name) field in the Context Item table (sn_smart_asmt_context_item). |
How metric categories are mapped
This tables shows the mapping used to move the existing metric categories to the section table in the assessment templates.
| Existing metric type | Mapped to the Section table |
|---|---|
| Name (Translated text) (Max length 255) | Name (Translated text) field. |
| Description (Translated text) (Max length 1000) | Description (Translated text) field. |
| Order (Integer) | Order (Order Index) field. |
How metrics are mapped
This tables shows the mapping used to move the existing metrics to the question table in the assessment templates.
| Existing metric type | Mapped to the Question table |
|---|---|
| Allow additional information (True/False) | Enable justification (True/False) field. |
| Data type (String) (Max length 40) | Based on the Data type field value, the appropriate question type reference is added to the Question table. Data type is string. |
| Details (Translated html) (Max length 8000) | Guidance statement (Translated html) field. |
| Question (Translated text) (Max length 512) | Label (Translated text) field. |
| Mandatory (True/False) | Is mandatory (True/False) field |
| Max (Integer) | Max number (Decimal) field |
| Min (Integer) | Minimum number (Decimal) field |
| Order (Integer) | Order (Order index) |
How metric types are migrated to question types
After migration, all Question records are set as data type Text.
After migration, all Question records whose source metric is template/Numeric-scale are set with a response layout of Horizontal.
This tables shows the mapping used to move the existing metric types to the question types in the assessment templates.
| Existing metric type | Mapped to |
|---|---|
| Attachment | Attachment |
| Choice | Drop-down list |
| Date | Date |
| Date/Time | Date/Time |
| Likert scale | Radio button |
| Multiple selection | Check box |
| Numeric scale | Radio button |
| Reference | Reference |
| Yes/No | Radio button |
How fields are mapped
This tables shows the mapping used to move the existing fields to the question table in the assessment templates.
| Field in the existing table | Mapped to the Question table |
|---|---|
| Reference table | Table field. |
| Condition | Filter condition field. |
How metric definitions are mapped
This tables shows the mapping used to move the existing metric definitions to the choice table in the assessment templates.
| Metric definition in the existing table | Mapped to the Choice table |
|---|---|
| Display | Text label field in the Choice table (sn_smart_asmt_response_option) |
| Order | Integer data type is mapped to the Order field in the Choice table that is based on the same ascending sequence of the template-definition records in the Value field that is associated with a particular template. |
How assessment metric templates are mapped
Only templates where the Allow image field is set to false are migrated. No field mapping is done for this table.
Metrics whose data type is template are migrated as questions of the type Radio button if the Allow image field is set to false at the template level.
How assessment template definitions are mapped
This tables shows the mapping used to move the existing template definitions to the choice table in the assessment templates.
| Assessment template definition in the existing table | Mapped to the Choice table (sn_smart_asmt_response_option) |
|---|---|
| Display | Text label field. |
| Value | Integer data type is mapped to the Order field in the Choice table, based on the same ascending sequence of the template-definition records in the Value field that is associated with a particular template. |
