Vote for vMigrator
vMigrator is a tool that can assist users of VMware Infrastructure to migrate to the next generation platform. Migrations from ESX Server 2.5x to VMware Infrastructure 3 (VI3) can involve hours of downtime per virtual machine (VM), whether the upgrade is done on the existing hardware or the VMs are moved to a new server.
Migrating VMs from the ESX Server 2.5x platform to VI3 can be complicated, incur substantial downtime, and lower business productivity. vMigrator is designed to eliminate the challenges associated with porting VMs to a new platform. Currently, VMware cannot automate the process of migrating from VMware VirtualCenter 2 to VI3.
