You can upgrade, downgrade, or switch the class of a CI by modifying its
Class attribute.

## Vorbereitungen

Role required: sn_cmdb_editor, asset, or itil (In general, the roles required to update a CI)

## Warum und wann dieser Vorgang ausgeführt wird

Each class is defined with a unique set of attributes. This set consists of
attributes that were derived from the parent class, and additional attributes
defined for the class.

When you reclassify a CI, the following occurs.  
1. The set of attributes is adjusted to match the set of attributes of the newly assigned class. Attributes are added or removed as needed.
2. If any attributes are unique to the current class and are not defined in the newly reclassified class, they are lost.
3. A new record with the CI's current sys_id is inserted to the table of the new class, with the appropriate set of attributes for the class (the sys_id of the CI is retained).
{#t_ManuallyReclassifyCI__ol_qqg_b1t_ls}

Depending on the reclassification, the following occurs.  

Downgrade

:   The CI class is updated to a class that is higher in the class
    hierarchy, and the newly assigned class is a parent of the current
    class. For example, reclassifying a CI from the
    cmdb_ci_server class to the
    cmdb_ci_computer class.

    For example, the cmdb_ci_server class has
    attributes that the cmdb_ci_computer class does
    not have. During the downgrade, these attributes and their
    respective values are not included in the new CI record that is
    inserted into the cmdb_ci_computer class.

Upgrade

:   The CI class is updated to a class that is lower in the class
    hierarchy, and the newly assigned class is a derived child of the
    current class and has additional attributes. For example,
    reclassifying a CI from the cmdb_ci_computer
    class to the cmdb_ci_server.

Switch

:   The newly assigned class is in a different branch in the class
    hierarchy and has a different set of attributes than the current
    class. For example, reclassifying a CI from the
    cmdb_ci_linux_server class to the
    cmdb_ci_win_server class.

    A switch is a combination of a downgrade and an upgrade. For example
    if the CI is downgraded to the cmdb_ci_server,
    and then upgraded to the cmdb_ci_win_server
    class. Therefore, attributes are lost in the same manner as in a
downgrade operation.  
Hinweis:  
Avoid the CI class downgrade and CI class switch operations as those can lead to data loss. When automatic CI reclassification is enabled (which is by default), the [identification
process](https://servicenow-prod.fluidtopics.net/Z0vdyA7BYiBt_YX8qkVWyQ "The Identification and Reconciliation module provides a centralized framework for identifying and reconciling data from different data sources. It helps maintain the integrity of the CMDB and some non-CMDB tables when multiple data sources are used to create and update CI records.") can result in some automatic reclassifications which lead to data loss.

For information about CI reclassification by the Identification and Reconciliation
Engine (IRE) and related system properties that control the behavior of automatic CI
reclassification, see [Configure CI reclassification during IRE processing](https://servicenow-prod.fluidtopics.net/zRozBYxmxbwue3gCje1NMQ#c_CIReclassification "During the Identification and Reconciliation Engine (IRE) CI identification process, a CI might need to be reclassified to a different sys_class_name type. By default, CIs are reclassified automatically. If automatic reclassification is disabled, then the CI is not reclassified and the system generates a reclassification task for your review.").

## Prozedur

1. Locate the CI that you want to reclassify and display it in a list view.  
   You can use the application navigator. Or for example, if the CI is a server, then in the navigation search box, type <kbd class="ph userinput">cmdb_ci_server.list</kbd> to display the CI in the Servers view.
2. Ensure that the Class field is displayed in the list.  
   If you do not see this attribute, personalize the list to add the Class field.
3. Double-click the Class value for the CI, and select a new class.
4. Click the green check box to confirm your selection.
