## Summary of Resolving cloning issues in Indoor Mapping instances

When cloning an Indoor Mapping source instance to a target instance in ServiceNow, workplace administrators may encounter missing attachments and data discrepancies.
These issues primarily affect Indoor Mapping tables and related workplace experience applications such as Map Studio, Workplace Central, Reservation Management, Services Kiosk, Move Management, and Service Delivery for Mobile.
Show full answer Show less  

## Cause

The cloning process excludes certain critical tables and attachments by default. Specifically, the System Clone or Clone Request records do not preserve data from the Attachment \[sysattachment\] table, nor from the Font \[snmapcorefont\], Layer \[snmapcorelayer\], Outdoor style \[snmapcoreoutdoorstyle\], and Tile \[snmapcoretile\] tables. This leads to incomplete data and missing attachments in the cloned target instance.

## Resolution Procedure

* **Export data from the source instance:** Log into the source Indoor Mapping instance and export XML files for the following tables:
  * snmapcorefont
  * snmapcoreoutdoorstyle
  * snmapcorelayer
  * snmapcoretile
* **Import data into the target instance:** Log into the target instance, switch the application scope to Indoor Mapping, and import the exported XML files to restore missing data and attachments.
* **Address JSON file discrepancies:** After importing, verify that JSON files in the Styles column of Outdoor styles do not have missing attachments. If issues persist, repeat the export/import steps or follow preservation steps below.
* **Preserve data to prevent future issues:** In the source instance, navigate to Clone Admin Console \> Clone Definition \> Preserve Data and add the four key tables (snmapcorefont, snmapcorelayer, snmapcoreoutdoorstyle, snmapcoretile) to the preserve data list.
* **Update clone profiles:** Add your clone profiles to the Preserve Data configuration to ensure these tables' data is maintained during instance cloning.

## Practical Impact for ServiceNow Customers

By following these steps, ServiceNow customers using Indoor Mapping can avoid data loss and attachment issues after cloning instances. This ensures that workplace applications relying on Indoor Mapping data function correctly and maintain a consistent user experience across cloned environments.  
After cloning a Indoor Mapping source instance to a target instance, workplace administrators may observe missing attachments and data discrepancies in their target instance.

## Symptom

Administrators can clone a source Indoor Mapping instance to a target Indoor Mapping instance. For more information, see [cloning an instance](https://www.servicenow.com/docs/access?context=system-clone-landing&version=australia&pubname=australia-platform-administration&ft:locale=en-US).

Before cloning your Indoor Mapping source instance to a target instance, preserve data for each of the listed tables in your source instance. This helps in preventing missing data and attachments in your target Indoor Mapping cloned instance tables.  

## Cause

Data discrepancies and missing attachment issues are observed after you have cloned your target instance. The System Clone \[clone_instance\] record or Clone Request \[sn_instance_clone_request\] record in the source instance
excludes the Attachment \[sys_attachment\] table and doesn't preserve data in the Font \[sn_map_core_font\], Layer \[sn_map_core_layer\], Outdoor style \[sn_map_core_outdoor_style\], and Tile \[sn_map_core_tile\] tables.These
issues also affect workplace experiences in Indoor Mapping Map Studio, Workplace Central, Workplace Reservation Management portal, Workplace Services Kiosk, Workplace Move Management, and Workplace Service Delivery for Mobile.

## Resolution

### Procedure

1. Log in to your source instance.
2. Export the list of records in each listed table as XML from the source instance:  
   * sn_map_core_font
   * sn_map_core_outdoor_style
   * sn_map_core_layer
   * sn_map_core_tile
   {#troubleshooting-clone-issues__ul_ulv_2m4_5jc}

   For more information, see [Export data from a list](https://www.servicenow.com/docs/access?context=export-list-data&version=australia&pubname=australia-platform-administration&ft:locale=en-US).
3. Log in to the target instance.
4. In the target instance, update your application scope to Indoor Mapping.
5. Import the XML files to the target instance.  
   Note:  
   After importing the XML files, it's observed sometimes that there's no data in the JSON files. The JSON files stored in the Styles (style) column of the Outdoor styles \[sn_map_core_outdoor_style\] show missing attachments. To prevent missing attachments and data discrepancies, perform steps 6-7.

   For more information about
   how to import XML files, see [Import data from XML](https://www.servicenow.com/docs/access?context=c_ExportAndImportXMLFiles&version=australia&pubname=australia-platform-administration&ft:locale=en-US).
6. To avoid future clone issues, preserve data in the following tables:  
   * sn_map_core_font
   * sn_map_core_outdoor_style
   * sn_map_core_layer
   * sn_map_core_tile
   {#troubleshooting-clone-issues__ul_uy5_gjn_5jc}
7. To preserve data in sn_map_core_font, sn_map_core_outdoor_style, sn_map_core_layer, and sn_map_core_tile tables perform the following steps:  
   1. Log in to your source Indoor Mapping instance.
   2. Navigate to AllClone Admin ConsoleClone DefinitionPreserve data.
   3. Select New.
   4. On the form, fill in the fields:  
      {#troubleshooting-clone-issues__table_lc2_4vh_vjc__entry__2}
