IRE reclassification

[EDCT]

Hi,

My org is bringing in an integration which will use the IRE to insert and update CIs in the computer table.

I would like to understand how reclassification works; will ServiceNow be able to upgrade the class of a new CI to e.g., Unix Server, or Personal Computer and how will it make this decision.

Is there a way to see the default logic behind this what fields it looks at, what it’s looking for etc.?

And to understand if this is logic which can be customised.

Thanks.

When you change a Configuration Item (CI) to a new class, here’s what happens:

1. **Attributes Adjusted**: The CI will get the set of attributes that belong to the new class. Some attributes might be added, and others removed.

2. **Attributes Lost**: If the new class doesn’t have certain attributes that the current class has, those attributes and their values will be lost.

3. **New Record Created**: A new record is made for the CI in the new class, but it keeps the same unique identifier (sys_id).

Depending on what type of change you’re making:

- **Downgrade**: Moving to a higher-level class in the hierarchy. For example, from a specific type of server to a more general computer class. Attributes specific to the current class are lost because the new class doesn’t support them.

- **Upgrade**: Moving to a lower-level class in the hierarchy. For example, from a general computer class to a more specific server class. The new class will have extra attributes, and the CI will gain these new attributes.

- **Switch**: Moving to a class in a completely different branch. For example, from a Linux server class to a Windows server class. This process combines both downgrade and upgrade, so attributes specific to the old class will be lost.

**Important Note**: Be cautious with downgrades and switches because they can lead to losing data. Automatic CI reclassification might happen, which can result in data loss as well. Check the settings for how automatic reclassification is handled to avoid unwanted data loss.

Thanks both, however I was looking for information on the criteria the IRE uses to reclassify CIs. It looks to be using OS to place CIs in Windows or Linux classes but this is just observation.
