To gather the information needed to identify the required compute resources in Azure when migrating an SAP environment from VMware vCenter, you should use Azure Migrate and SAP EarlyWatch Alert reports. Azure Migrate helps assess on-premises workloads, including VMware VMs, in terms of CPU, memory usage, and performance history, and provides insights on how they will perform and how much they will cost in Azure. SAP EarlyWatch Alert reports provide monitoring data specific to SAP systems, which is crucial for understanding the current resource usage and performance of the SAP environment.
To recommend suitable sizes for the Azure virtual machines that will host the SAP ECC production system, it is essential to review sections that provide detailed information on the current hardware utilization and configuration. The 'Hardware Capacity' section contains performance data such as CPU and memory utilization, which are critical for determining the necessary resources for the virtual machines. The 'Hardware Configuration under Landscape' section provides essential details about the hardware setup, such as the type of CPUs and other system specifications that help in identifying the most appropriate and compatible Azure VM sizes. These two sections together provide a comprehensive understanding of both the performance and configuration requirements necessary for the migration.
Azure Site Recovery is an appropriate solution for migrating SAP application servers to Azure as it supports minimal downtime and limited changes to the environment. Azure Site Recovery is typically used for disaster recovery of on-premises machines and Azure VMs, but it can also be employed for migration purposes. By replicating the SAP application servers into Azure, the transition can be managed efficiently and with reduced downtime. This method aligns well with the requirements of maintaining minimal downtime and changes to the environment during migration.
To check the usage of the source system hardware such as CPU, memory, and network in an SAP system, the appropriate transaction to run from the SAP GUI is OS07N. This transaction is specifically designed for monitoring the operating system's activity and provides detailed statistics on the hardware usage. Other options like SM51, DB01, and DB12 serve different purposes, such as displaying application servers, analyzing exclusive lock waits, and monitoring database backups respectively, and are not suitable for this requirement.
The SAP Solution Manager is a centralized, robust application management and administration solution designed to support, operate, and monitor SAP enterprise solutions. It integrates various tools, methodologies, and access to SAP systems, making it the best choice for getting a comprehensive list of all applications in an SAP environment. It provides detailed information about all connected systems within the SAP landscape, which is essential for planning the migration of applications to Azure.
