Businesses’ objectives for moving their workloads to the cloud must be taken into account. Cost reduction, enhanced business security, efficiency, agility, and compliance are among the key reasons. For a successful migration, legacy migration should align with clear business priorities.

Right Choose Migration Strategies

Businesses can select from a variety of migration models based on the complexity of their workload and legacy applications, such as:

• Rehosting or Lift-and-Shift: This legacy migration strategy involves companies moving their workloads and apps exactly as they are to the AWS or VMware cloud.
• Re-Platforming: This migration strategy makes only minor changes to the applications without changing the fundamental logic.
• Refactoring: The application code and architecture are updated in the legacy migration approach to guarantee compatibility with cloud-native services and enable smooth operations.
• Rebuilding: Applications are created from scratch on a new cloud platform as part of the rebuilding legacy migration approach. To increase overall performance, the architecture has been completely redesigned.
• Replacing or Retiring: The applications in this legacy migration strategy have already been decommissioned, meaning they are no longer operational. Therefore, they are either removed from the infrastructure or replaced with a brand-new, alternative solution.

Legacy Workload Migration to VMware: Updating Infrastructure for Smooth Operations

For companies that wish to update their infrastructure while maintaining total control over their workloads and applications, the VMware platform is perfect. Here are the core steps of a legacy system migration to a VMware strategy:

Rehosting and Virtualizing Legacy Workloads

Legacy workloads are converted from traditional physical hardware, and VMware-based virtual machines are used to replace traditional physical hardware for legacy workloads. To guarantee a seamless and interruption-free migration process, tools such as VMware vCenter Converter are utilized. Businesses can overcome the limitations of legacy systems by virtualizing hardware-dependent applications.

Different VMware Management Tools

Different VMware management tools used in legacy application migration are:

• vMotion: It enables live migration of workloads from traditional physical servers and the VMware platform without any disruptions.
• vCenter Server: IT teams can easily manage virtual machines (VMs) with centralized administration, thanks to vCenter Server, which also enables performance analysis and resource allocation optimization.
• High Availability (HA) for vSphere: vSphere HA enables constant uptime by providing automated failover protection.

Disaster Recovery and Backup

The ability of VMware to recover from disasters is well known. Because legacy applications lack resilience, companies can utilize VMware features such as snapshots, replication, and fault-tolerant systems to secure migrated legacy workloads after they are virtualized.
