PRESERVING AND MODIFYING VIRTUAL MACHINE SETTINGS IN REPLICATION-BASED VIRTUAL MACHINE MIGRATION

Aspects of the disclosure are directed to modifying and preserving virtual machine settings at a target computing environment as virtual machine settings change for a migrating virtual machine. The migration system balances matching the most up-to-date settings of the virtual machine in its source environment, with making changes as necessary to the settings of the virtual machine so that the settings are compatible with a target computing environment, updating the settings as needed. The migration system can continuously or periodically monitor changes in source virtual machine settings and/or in the source or target computing environments, and update target virtual machine settings up to the point at which a cut-over operation is performed and migration is complete.
