Developed as part of the broader open-source ecosystem by Vexxhost, Migratekit is an open-source command-line interface (CLI) tool with a singular focus: expediting and streamlining the migration of virtual machines from VMware to OpenStack environments with minimal service interruption.
The tool is the result of a concerted effort to facilitate a migration process where the majority of data transfer occurs without impinging on the virtual machine’s operational uptime, thereby reducing the downtime to the narrowest margin during the final transition phase.
Migratekit operates through a two-phase approach:
Phase 1: Online Data Movement
During this phase, Migratekit performs the bulk of the data transfer while the virtual machines remain active. This approach is crucial for maintaining operations and reducing the amount of downtime required for the migration.
Phase 2: Cutover Completion
The final phase involves a brief planned downtime to finalize the migration. This stage includes the synchronization of any remaining data and the transition of VM instances to the OpenStack environment.
It works with any OpenStack deployment, Migratekit’s methodology is developed from a need for continuous service availability and the complexities of infrastructure migrations. It offers a practical solution for minimizing the impact on services during the shift to a new cloud platform.
