Greetings,
Kindly share your experience and knowledge regarding network migration best practices and plan
Ii have to migrate a ring of core switches 6509 to new catalyst 9607.
Which method would be better?
I plan to go for duplicating all existing core 6509 configurations into new 9607 switches and then one by one replace the existing 6509 core switches connected in ring with preconfigured 9607.
And then test if the ring and performance is as before.
Is this a good way to go?

Hi
There are multiples ways to achieve these migrations.
Can you share a quick sketch of your design?
Are you running any dynamic routing protocol?
One of the solution would be:
- replicate your 6k config to your 9k switch
- shutdown all SVIs on your 9k
- interconnect 6k and 9k using a dynamic routing protocol (ospf, bgp, eigrp...)
- migrate vlan by vlan:
--> when you want a vlan to go through new 9k switches, shut svi on 6k and no shut on 9k.
So new vlan will be up on 9k but still able to reach svis on 6k due to routing interconnect and if something goes wrong just do the invert.
Again this depends on how you're design is, what network services you're running/want to migrate...

Hi Francesco,
Instead I plan to go for duplicating all existing core 6509 configurations into new 9607 switches and then one by one replace the existing 6509 core switches connected in ring with preconfigured 9607.
The 6509 core switches in different location are connected in ring topology and hence I would like to do a one by one migration instead of parallel one
And then test if the ring and performance is as before.
Is this a good way to go?
