Hi all,
We need replace to a pair of switches with new ones without interrupting traffic.
In order to do that , for some minutes all 4 switches will be interconnected between them - but we need to avoid stp recalculations - has anybody done that? any ideas how to design the migration without any stp recalculations ?
Some info:
We got 2 dc and we can work on backup while traffic flows to dc 1 and then we need to switch traffic to dc2 and work on dc1 with replacements - please see the basic design:![23-07-40.jpg 23-07-40.jpg](https://community.cisco.com/t5/image/serverpage/image-id/12025iE7A66A801996BE23/image-size/large?v=v2&px=999)
Thank you all !
