Migration to SD-Access

[techno.it]

Hello everyone,

I am looking for a guidance on Cisco SD-Access migration from traditional network. I am working on building new SDA fabric physically alongside to legacy network. SDA-access consists of new switches. Once that Sd-access is all setup and happy, then we would incrementally cut over and migrate the users. Migrated Users should be able to talk to servers in old DC network and be able to go to internet through the firewall.  We don't want to do new IP addressing scheme.

Can anyone give step by step guide and migration strategies

Existing setup is

Firewall-----6500 (CORE)---trunk---- 2950 (access switch)

                           |

                     Servers

New network has

9500 as fabric borders ( Stackwise)

9300 as fabric edge.

techno.it,

There are a couple of very good migration sessions in the Cisco Live On-Demand Library:

BRKCRS-2812 : Cisco SD-Access Integrating with Your Existing Network (https://www.ciscolive.com/global/on-demand-library.html?search=BRKCRS-2812&search.event=ciscoliveemea2020#/session/1564677156116001JpyT)

BRKCRS-3493 : Real World Route/Switch to Cisco SD-Access Migration Tools and Strategies (https://www.ciscolive.com/global/on-demand-library.html?search=BRKCRS-3493#/session/1571888607137001yDeW)

I would also take a look at this Best Practices session:

DGTL-BRKCRS-2502 : Best Practices for Design and Deployment of Software Defined Access (SDA) (https://www.ciscolive.com/global/on-demand-library.html?search=BRKCRS-2502#/session/1573153542505001JVhS)

Feel free to reach out if you need additional assistance.

i have same questions , currently we have same setup , ISE, WLC , servers are connected to core switch . I am confused about fusion integration , is it correct way to keep existing core as fusion & connect trunk unlink to border router , use that uplink for BGP layer 3 (VN communication) and also same link for L2 handoff during migration ?
