Downtime was once a thorn in the process of migrating a virtual machine, but live migrations put a stop to that. Now, live migration eliminates downtime, but there are still ways to improve how you move VMs from one physical host to another.

Hyper-V live migrations. There are strategies that can speed up and automate the process and ways to protect the migration.

These five quick links are different ways that your Hyper-V live migration can be improved in speed, security and more.

VM live migration changes in Windows Server 2012 R2
Windows Server 2012 included many important upgrades over its predecessor, including the ability to optimize live migrations. Both WS 2008 and 2012 used TCP/IT as a default. But in 2012 R2, VM memory is compressed before it is copied over the network.

PowerShell cmdlets overcome Hyper-V Live Migration limitations
If you're running Windows Server 2008 R2, you may be missing out on some of the live migration improvements in WS 2012. But you don't have to. Windows PowerShell cmdlets work around some of the limitations, helping migrate multiple VMs, schedule the migration and more.

Put your live migrations in the fast lane
Live migrations have erased the downtime that used to happen when moving a VM and its storage from one host to another, but it can still be a time-consuming process. You can speed up and automate this process by using PowerShell and SMB 3.0 file shares.

Virtualization best practices that accelerate virtual machine migration
Virtual machine migration can seem effortless and instant, but according to an Enterprise Management Associates' report, many attempted migrations didn't achieve immediate migration. But using these virtualization best practices, such as virtual machine management software, can help quicken the process.

Have you done all you can to secure VM live migrations?
Choosing the right authentication protocol is key for securing your VM live migrations. You can also take other steps, such as using a dedicated network, to help improve the speed and security of your live migrations.
