Hi,
I am a traditional networking guy, and start studying on the NSX-T. After few weeks of studying, I am now familiar to the NSX-T components and able to build a NSX-T environment from scratch.
However, I am still struggling on how to step-by-step move from traditional networking to NSX-T 3.0 with minimal impact to existing traditional infrastructure.
The 'minimal impact' means:
Glad if anyone can share some document / idea about it.
Here is my thought, I don't know if it's valid or not.
1) Regarding to the 1st requirement:
2) Regarding to the 2nd & 3rd requirement:
I am not sure if my thought is valid or not. Glad if anyone can share yours experience 🙂

2) Regarding to the 2nd & 3rd requirement:
Majority of the case we can change MTU on fly . There are few limitations with server profiles (blade servers for specific vendors ) and legacy stack switches . MTU change is must in NSX environment. We don't support fragmentation of packets . So decreasing MTU won't help . There are transit VNI path between T1 and T0 and tunnel connectivity will show as down . DVS MTU ->TOR MTU>L3 if we are terminating overlay networks also should have consistent MTU.

Dear Stree,
Thanks so much for your reply!! 🙂
Sound my idea is basically valid. But do you have some real world example that how does enterprise migrate to NSX-T from traditional network. It's great if there is another more practical way to do it...

Hi Sree,
Thanks a lot for answering my questions!! 🙂
I think I have to read on more detail about the bridging (portgroup to VNI mapping).
Thanks again, and have nice day~
