Migration to NDFC

[Jayashanker warrier]

Greetings, 

Can you please let me know 

If i have already a VXLAN fabric configured via CLI and i am introducing NDFC

a) can i preserve the configs when i discover and add them to the fabric in NDFC (i think i can)

b) if a) is yes then can i also use NDFC for future changes/additions... (after they are discovered and included in the fabric)

c) if b) is NO then the only option for me is to create and configure templates in NDFC and re-deploy so that the fabric can now be managed by NDFC...

Hello @Jayashanker warrier 

You can preserve your existing VXLAN EVPN fabric configuration when introducing NDFC by performing a brownfield discovery.

The Brownfield migration may take some time to complete since it involves collecting the running configuration from switches, build the NDFC configuration intent based on these, consistency checks etc.

Any errors or inconsistencies that are found during the migration is reported in fabric errors. The switches continue to remain in the Migration mode. You should fix these errors and complete the migration again by clicking Deploy until no errors are reported.
