数据卷管理（DVM）提供支持转换前和转换后阶段的各种功能。一个中心工具是SAP Solution Manager中的SAP DVM工作中心（DVM WoC），包括特别关注SAP HANA的工具。引导式自助服务：您可以生成最佳实践文档，以确定在转换之前可以在SAP系统中最有效地减少的数据。您可以在转换后使用相同的工具为DVM策略制定蓝图。重组和压缩：您可以在没有SAP HANA上下文的情况下使用此工具，以模拟通过重组表或数据库或压缩数据库而获得的节约。此外，您可以模拟系统的未来系统大小。这对于预测任何计划措施可能造成的影响非常有用。除了DVM工作中心外，Data Volume Management还提供服务，让您了解数据分布和质量，并提供服务帮助您为系统环境制定DVM路线图。所有服务都允许您对内容和数据量管理做出灵活的决定。其他信息有关更多信息，请参阅SAP帮助门户网站http://help.sap.com/solutionmanagerSAP Solution Manager应用程序帮助应用程序帮助（英文）应用程序操作。有关数据卷管理的一般信息，请参阅SAP社区网络，网址为http://wiki.scn.SAP.com/wiki/diisplay/TechOps/Data+Volume+Management。3.5维护计划器概述您必须使用维护计划器转换为SAP S/4HANA。Maintenance Planner生成软件更新管理器（SUM）用于执行转换的下载文件（加载项、软件包、DBD和堆栈配置文件）。特别是，Maintenance Planner会检查转换是否支持以下项目：系统中的附加组件系统中的活动业务功能行业解决方案如果上面列出的任何项目都没有有效的转换路径（例如，尚未为转换发布附加组件），MaintenancePlanner会阻止转换。检查后，Maintenance Planner创建堆栈配置文件（stack.xml）。SAP S/4HANA 1809转换指南准备转换P U B L I C 19 注意：为了生成stack.xml，您需要拥有SAP S/4HANA许可证。您可以在没有许可证的情况下执行上述检查，但不能在没有许可的情况下使用Maintenance Planner创建stack.xml。有关详细信息，请参阅Maintenance Planner
Data Volume Management (DVM) offers various capabilities supporting the pre- and post-conversion phases. One central tool is the SAP DVM Work Center (DVM WoC) in SAP Solution Manager, including tools with a special focus on SAP HANA. Guided Self Service: You can generate a best practice document to determine data that can be reduced most efficiently in an SAP system before the conversion. You can use the same tool after the conversion to develop a blueprint for a DVM strategy. Reorganization and Compression: You can use this tool without a SAP HANA context in order to simulate the savings gained by reorganizing tables or databases or compressing the database. In addition, you can simulate the future system size of your system. This is useful for a forecast of the impact any planned measures may cause. Beside the DVM Work Center, Data Volume Management offers services to give you an overview of your data distribution and quality as well as services to help you to develop a DVM road map for your system landscape. All services allow you to make flexible decision about your content and data volume management.

The Maintenance Planner generates the download files (add-ons, packages, DBDs, and the stack configuration file that the Software Update Manager (SUM) uses to do the conversion. In particular, the Maintenance Planner checks if the following items are supported for the conversion: Add-ons to your system Active business functions in your system Industry solutions If there is no valid conversion path for any of the items listed above (for example, an add-on is not released for the conversion yet), the Maintenance Planner prevents the conversion. After the check, the Maintenance Planner creates the stack configuration file (stack.xml). Conversion Guide for SAP S/4HANA 1809 Preparing the Conversion P U B L I C 19 Note In order to generate the stack.xml, you need to have an SAP S/4HANA license. You can do the above checks without a license, but you cannot create a stack.xml with the Maintenance Planner without a license. For more information, see the Maintenance Planner
