Method and system for implementing application migration between platforms

technical field

Background technique

With the continuous development of information technology (Informationtechnology, IT) and industrial technology, the replacement speed of computer hardware and software is getting faster and faster, and the performance-price ratio is getting higher and higher. In order to meet the needs of enterprise business development, the frequency of enterprise replacement of software and hardware is also increasing. Therefore, migrating applications on the old platform to the new platform is an important link in enterprise upgrading and updating. How to ensure smooth migration of applications, reduce migration risks and workload, and reduce total cost of ownership (TCO) is the key to winning customer satisfaction and willingness to use.

When migrating applications across platforms, applications often require certain configuration modifications. For example, in PCIE (Peripheral Component Interconnect Express, high-speed peripheral component interconnection) switching architecture servers, there are some differences between PCIE, Ethernet, and InfiniBand. Traditional applications are developed based on Ethernet and InfiniBand architectures, and some configuration modifications are required for migration and deployment to PCIE architectures. In the prior art, as shown in Figure 1, it is a physical to physical (Physicaltophysical, P2P), physical to virtual (Physical to virtual, P2V), virtual to virtual (Virtual to virtual, V2V) system migration solution, which can migrate any x86 architecture server The Windows operating system and domain controller information as well as applications and data can be quickly migrated to HP's latest ProLiant server platform. At the same time, the system migration between physical machines and virtual machines is supported through ProliantEssentials tools and virtual machine (Virtual Machineware, Vmware) technology. However, this technology can only support the HP ProLiant platform, and does not support the migration from traditional servers to PCIE switching architecture servers, nor does it support the system migration of the reduced instruction set computer (RISC) platform, and it cannot optimize computing resources during the migration process; An application migration solution provided in Figure 2 can realize cross-platform migration of applications, but this technical solution only migrates the operating system (Operationsystem, OS) platform and system services on which the application depends, and cannot migrate application data, and cannot be migrated Optimizing computing resources during the process.
