What's New

vCloud Director Extender 1.1.0.1 provides the following new features:

Support for vCenter Server 5.5 U3 to enable migration of on-premise VMs to a cloud provider environment.
Test cutover after a warm migration that allows consistency check of the target VMs by powering them on and running the necessary tests.
Warm migration with seed enables offline transfer of VMDK files as seed images to a target cloud and import of the seed images to the cloud. Using seeds reduces the time to perform initial transfer of the VMDK files and benefits the migration of large VMs or on-premise data centers with low WAN connectivity.
Multiple appliance configurations that allows DC extension for more than one virtual data center.
Generating a support bundle to aid when you are troubleshooting vCloud Director Extender issues. For more information, see vCloud Director Troubleshooting.
