VMware NSX for vSphere to NSX-T Migration – End-to-End User Defined Topology – Config Translation Failed – Reason: Topology Plugin
In a previous post focusing on the VMware NSX Migration Coordinator (VMware NSX for vSphere to NSX-T Migration – End-to-End User Defined Topology), I detailed the end-to-end process required to migrate VMware NSX Data Center for vSphere (NSX-V) to VMware NSX-T Data Center (now simply VMware NSX as of 4.x) and, more specifically, the ‘User Defined’ option, which allows customers to map NSX-V Edge Services Gateways (ESGs) and Distributed Logical Routers (DLRs) to NSX-T components (e.g., Tier-0 or Tier-1 Gateways). To perform this mapping, customers can either a) upload a pre-defined JSON file or b) use the NSX UI to select the appropriate Tier-0/Tier-1 Gateway via drop-down menus.
The previous post utilised VMware NSX Data Center for vSphere 6.4.13 and VMware NSX-T Data Center 3.2.1, however, labbing this in readiness for an upcoming customer engagement required VMware NSX Data Center for vSphere 6.4.14 and VMware NSX (formerly NSX-T) 4.0.1.1; herein lies the identification of a possible bug when using the UI to map ESGs/DLRs to Tier-0/Tier-1 Gateways.
