NSX Migration from VCF on premises to IBM Cloud

[jvm2016]

can you also comment on the following for the use of nsx in migration from client side to cloud (IBM using VCF).

consider a scenerio wherein client side is also using nsx and using universal construct of transport zone and universal logical switch this can be extended to ibm cloud .

this will avoid unnecessary reconfiguration of ip after workload migrations i think this is one of the advantages of NSX using both source and destinationside . what you suggest??

however how we can avoid such reconfigurations of ip when only destination(i.e ibm with VCF) has nsx configuration and client side using vlan based networking .

Thanks for your suggestions.

"how we can avoid such reconfigurations of ip when only destination(i.e ibm with VCF) has nsx configuration and client side using vlan based networking"

This is what VMware Hybrid Cloud Extension (aka HCX) provides (https://cloud.vmware.com/vmware-hcx).  The ability to connect your on-prem VCF with your public cloud and to create a seamless network extension with the bi-directional migration of workloads.

IBM has a couple of white papers on this:

Thanks while iam checking this can you suggest if any componet of HCX(may be L2 concentrators) is synonymous to universal logical switch of NSX.

HCX has a cloud-side component that runs in the VCF instance (private or public cloud) along with an OVA that gets deployed in the vSphere cluster from which you will migrate your workloads.  A logical switch is then created to bridge the two sides and stretch the on-prem network into the cloud.  It also includes WAN optimization features that can help with workload migrations.  So conceptually, it is akin to a universal logical switch in that it is a logical switch that extends across the cloud.
