vmothion between the vxrail boxes

The easiest and simple method is:

     Attach shared storage (iSCSI/NFS) to both clusters.

     Storage vMotion VM to the shared storage

     Unregister VM form Source vCenter

     Brouse the Shared storage on Target vCenter, Import VM

     Storage vMotion to the Target VSAN.

There are many other ways to do it.

Hi,

Do you use an extended vCenter with two VxRail clusters? Then it's possible to migratie online vm's between the clusters.

Cheers!

Hi Vincent,

can u please elaborate about Extended Vcenter. please provide me if there is any link for configure the same.

i was trying to add one VxRail host to another for migration it is not happening.

Thanks,

Murugan. S

See this

https://www.virtuallyghetto.com/2016/05/automating-cross-vcenter-vmotion-xvc-vmotion-between-the-same-different-sso-domain.html

you can vmotion between vxrails without sso integration using this method.

i know this works well.

or you can use RP4VM if you can accept a short down time

Hi Muragan,

Create on one host in cluster 1 a new vmotion vmkernel portgroup in subnet X. Do the same for one host in cluster 2. It's important that both vmotion portgroups are in the same subnet X. Temporarely disable the default vmotion portgroup on these two hosts and enable the new one. Because the name of a vmotion portgroup should be unique choose e.g. vmotion01 en vmotion02. The name doesn't matter for vmotion functionality. Now it's possible to vmotion/storage-vmotion & network-vmotion your vm online to the other cluster. Of course in the source and destionation cluster the same vm guest portgroup-id(vlan) should be available.

If you have enough resources available in both clusters it is wise to vmotion both hosts with the temporarely vmotion kernel portgroups empty before disable the default vmotion vmkernel portgroups. This because the hosts are temporarely isolated from the other hosts in the cluster to  vmotion vm's within the same cluster.

When you're finished with migrating the vm's, you can disable the temporarely vmotion vmkernel portgroups and enable the defaults again.

Cheers!

Hi,

Can you elaborate more on the other ways that we can follow for such scenario migrating VMs from one VxRail to another ?

Could you please provide a little bit more information about the environment:

     The vCenter:

          External or internal?

          One or two vCenters?

          Shared vMotion VLAN?

Here is a great overall guide on migrations to vSAN. Similar principals can be applied VxRail to VxRail.  Storage and Availability Technical Documents

Hi,

          External or internal?

the old VxRail has its internal vCenter which cannot be working as customer supplied vCenter

          One or two vCenters?

now i have only one vCnter for th old appliance

           Shared vMotion VLAN?

no, separate VLAN for vMotion and vSAN

So there will be 2 vCenters, both internal for old and the new VxRails?

Are both environments vSphere 6.0?
