I am doing VCF In-place migration from NSX V2T. During assessment I am having an error saying that SDDC is not AVN aware. Is there any way to inject AVN info into SDDC manager. Please let me know anyone.

More information:

1. VCF, Vcenter, ESXi upgrade done by VCF team.
2. Its connected by BGP to ToR.
3. Consists of one LB, 2 edges, 1 DLR at NSX-V env.
4. VXLAN backed Region A/X present in VCF.
