Hyper V Replication to move a server to new hardware


I have a virtual server 2008 domain controller running on Hyper V 2012.

I have got a new server to replace the host and was wondering if the best route to move the VM is to setup hyper v replication from the old to the new.

Once the replication has completed i can then turn off the old server and turn on the VM on the new hardware.

Does this sound ok?

Importing the VM will be*significantly* faster. Replica is not a good tool for this use.

Wont replication allow me to keep the server down for a smaller amount of time though?

I can set the replicaiton going a few days prior to change over day and then the downtime is limited to me turning off the old VM and powering on the new one?

If i export the VM will need to be down whilst it exports and then files copied to the new server and the imported again?

2012 no longer requires an export before import. So you can import then cut over.

Sorry not sure i understand.

To export i thought you had to power down the VM and then export.

Then move the files to a new host and import.

Are you saying i can import across the network directly from the source?

does this cope with any file changes whilst the import is occuring or will i still need to power down the vm?
Cliff GaliherCommented:
Power down the VM to have a consistent copy.

Thats my point.  Its a large VM so it will take a while to import so while its doing this the server is down.

If i go down the replication route the server wont have to be down for as long......
Cliff GaliherCommented:
Its far more fragile. Unless the server is in a cluster, you already have maintenance windows for patching, etc. This is no different. I'll never understand why people ask for advice then try to argue with it. Your call. It isn't my decision, and I have no stake beyond trying to help you choose the right path.
