These maps are useful for planning change or migration, as well as analyzing the continuity and availability of services. The maps are useful in the following cases: Planning the migration of an entire service instance or its segments : Use the map to see which configuration items (CIs) need relocating or which CIs become redundant. Planning the upgrade or replacement of a CI : Check the map to see what other CIs are affected when the CI is non-operational during maintenance. You can assess and plan the downtime or make provisions to avoid the downtime.Because the same CI may be used for multiple application services, check the CI using the Dependency Views application. With this application, you can see all application services that a CI belongs to. Analyzing a service instance for high availability and continuity : Use the map to identify CIs crucial for the service performance. Decide if you want to fortify these CIs by creating clusters. Troubleshooting application services : Use the map to understand the impact of an issue and determine which CI is causing the problem. * **[Application service maps in classic Service Mapping](https://servicenow-prod.fluidtopics.net/pCozfOTzAZRGqwN_KEJkIw)** Maps offer you a visualization of data on configuration items (CIs) comprising application services, and relations and connections between these CIs. * **[View CI attributes in an application service map in classic Service Mapping](https://servicenow-prod.fluidtopics.net/tM~KnCcfQkq3VgSNW9VjEw)** An application service map displays attributes for each configuration item (CI) that is part of the application service, as well as for the application service itself. The attributes come from the CMDB. * **[View CI connection attributes in an application service map in classic Service Mapping](https://servicenow-prod.fluidtopics.net/OAlPexBAwY0OM8inlOAb5Q)** You can view attributes of connections between configuration items (CIs). * **[View the change history of application services in classic Service Mapping](https://servicenow-prod.fluidtopics.net/7KUinl4tyc2YyKqLg0fVSw)** You can view the changes made to an application service as a whole and to the individual configuration items (CIs) comprising the service. Change history is useful for maintenance, planning, or troubleshooting procedures. * **[Compare two versions of an application service in classic Service Mapping](https://servicenow-prod.fluidtopics.net/KHsDGaehfMHy2aUY8Fwybg)** You can see a summary of application service changes at a glance by comparing two versions of an application service. This feature is useful for checking the application service status before and after a certain change or problem. * **[View dependent application services in classic Service Mapping](https://servicenow-prod.fluidtopics.net/iGFK1duG1bNDwq0efXHBow)** Check which application services depend on an application service and open maps for dependent application services. * **[View contained application services in classic Service Mapping](https://servicenow-prod.fluidtopics.net/h4tIGY1szq1ReV31RxJ0nw)** A contained application service is a reference included into another, dependent application service. You can open the contained service map directly from within the dependent service map. * **[Check CI dependencies](https://servicenow-prod.fluidtopics.net/3Zm_tE2Dqyyyx4bwjXTUAg)** You can see if a particular configuration item (CI) is part of other application services and check if it depends on other CIs. * **[View the network or storage path in classic Service Mapping](https://servicenow-prod.fluidtopics.net/ABNd4ytuUXMoZDTmMaFm8w)** You can drill down to see objects behind a connection on a map for troubleshooting service performance or maintaining your network. This feature is not available for manually created services or for services on instances using Edge Encryption. * **[View the list of CIs belonging to an application service](https://servicenow-prod.fluidtopics.net/4nnVVtMsh6dT2SBF7qp6fg)** View a complete list of CIs that make up an application service, including CIs not shown on the application service map: tracked configuration files, endpoints, processes, and network devices. * **[Convert application service maps into PDFs](https://servicenow-prod.fluidtopics.net/vub_u1QnoTbRnZKb_VBK4A)** You may want to create a PDF for a map to share information about the service content with other people. PDFs are especially useful during the review and approve process for application services discovered by Service Mapping. * **[Modify view for an application service map](https://servicenow-prod.fluidtopics.net/WhV9fFRvYVeCfxwRO196Vw)** Customize a map view to display relevant information and increase clarity. **Related concepts** * [Review and approval of application service maps](https://servicenow-prod.fluidtopics.net/BjGtOsTta_Wo~8ykmxZngQ "After the Service Mapping administrator maps IT services and fixes errors in them, the administrator and the owner collaborate to review and approve the service maps. The review and approval process is available only for discovered and manually created service instances.") * [Application service completion](https://servicenow-prod.fluidtopics.net/oTiVA8bO~~ejaFfgU_iy9w "After an application service is reviewed and approved, you can define attributes that enhance its discovery, reflect its importance, and control access to it.") **Related tasks** * [Map multiple application services suggested by classic Service Mapping](https://servicenow-prod.fluidtopics.net/qFTEgnBYmx4N~e7Wi0hmtA "You can map multiple application services identified and suggested by Service Mapping in a single operation. This method suits your organization if you do not have much information about application services.") * [Map application services using tags with classic Service Mapping](https://servicenow-prod.fluidtopics.net/LP1_hSxqw0iYBN~sMLLWGQ "Use tags that help categorize and organize configuration items (CIs) in your organization to map application services. Tag-based mapping doesn't require configuring credentials or providing users with elevated rights.") * [Map multiple application services from a CSV file using classic Service Mapping](https://servicenow-prod.fluidtopics.net/0ElnFoss5kGCl7N1cGU5oA "This method suits you if your organization has performed cross-organization mapping and analysis and collected some information about planned service instances. If so, you can organize the collected information in a specific order and save it as a CSV file. Service Mapping extracts information from this file and creates potential service instances referred to as service candidates.") * [Map a single application service using classic Service Mapping](https://servicenow-prod.fluidtopics.net/8sD~6Bc3quESSBMeonfe4g "In addition to mapping application services in bulk, you can map individual, single application services by defining attributes for each application service. Use this mapping method if you already know or are planning to find out application service details. You must have Service Mapping enabled to map or review application services.") * [Fix application service errors in bulk](https://servicenow-prod.fluidtopics.net/AQZZC7bwEONc9WvfM9~Maw "Service Mapping classifies errors by their root cause, for example, missing credentials or task timeout. For a fast and efficient process, fix errors belonging to the same category in bulk.") * [Fix errors in individual application service maps](https://servicenow-prod.fluidtopics.net/mCyIAds3bqivvs99ielgpg "You can address discovery issues in each application service map individually.") * [Fine-tune application services to implement owner requests](https://servicenow-prod.fluidtopics.net/iBl4ZwvZMr6J_fUdsUa1Nw "As an administrator, you tweak and fine-tune maps based on comments from the application service owner.")
