Hi, Please help me to understand process to upgrade ACI fabric when using N9K-C9504 modular switches as spines. Below are the details of Spine 9504 chassis and leaf switches. SPINE: chassis: N9K-C9504 Slot 1 : N9K-X9732C-EX Slot 2 : N9K-X9732C-EX Slot 22 : N9K-C9504-FM-E Slot 23 : N9K-C9504-FM-E Slot 24 : N9K-C9504-FM-E Slot 26 : N9K-C9504-FM-E Slot 27 : N9K-SUP-A Slot 28 : N9K-SUP-A Slot 29 : N9K-SC-A Slot 30 : N9K-SC-A LEAF: N9K-C93180YC-EX Can I upgrade fabric just like non modular spines when using C9504 spine...? Or some other approach to be followed.
