Today was the last day I user wizard Hyper-V to activate the VM replication .. Why? Since today i did something i should have done a long time ago.. I made a script for enable VM replication for all machines on one server. The script going to selecting all ”running” machines, that not have replication enabled at the moment. Happy POSH:ing!
