we have 2 serperate vm enviroments, and we try to migrate hosts with vm`s from the old 6.0 enviroment to the new 6.7 enviroment.
this works , i remove a host ( with running vm`s ) from the old 6.0 and add it to the 6.7 enviroment.
when i try to migrate ( vmotion ) in the new enviroment from one host to the other host, vmotion fails at 21%
the only way it works is to shut down the vm and then migrate, this works.
only we would like to keep the vm`s running, is there a option to keep the vm`s running and migrate ( vmotion )
the old host is 6.0 and the new is 6.7 ESXI
thanks for all your reply
this is my error, but why can I vmotion migrate when the vm`s are powered off, and not when they are running.
networks have been checked and seem to be in order
The vMotion failed because the destination host did not receive data from the source host on the vMotion network. Please check your vMotion network settings and physical network configuration and ensure they are correct.
thanks for all the reply`s
The reason it works when the VM is offline is because you are doing an offline migration which does not require having to migrate the VM State and Memory to a new server. It is really just a file transfer that that point.
Take a look at this KB Article this should have an answer for your issue:
I just had the same problem. vMotion stuck @ 21% then the "The vMotion failed because the destination host did not receiver data from the source host..." message.
The vMotion interfaces all had the same MTU as did the switch ports.
The problem was some other admin had set a different VLAN ID on one of the hosts to the others.
Changing the source vMotion VLAN to match the target cleared the issue.
This is related to connectivity issues between the source ESXi and the destination one.
Make sure everything of this is working:
