Move UCS rack servers connected to Fiber Connect to different switch

[adildhar]

I have two Cisco UCS rack servers

(UCSC-C240-M4SX) connected and managed by Cisco UCS manager (6148). The servers have 10Gbps dual port converged NIC

(UCSC-MLOM-CSC-02). 
There is a plan to move these two servers to another location with different vendor layer 3 switch. The servers are associated with service profile and don't have HBA luns but are running production services. Can I move these to other switch? What steps would be involved?

The VIC adapters, CIMC, will still be expecting to talk to the FIs, and will not bring up the vnics with the FIs missing.

Since you are currenting in UCSM integrated mode, and taking the servers into stand alone mode, you will need to disassociate the service profiles (taking care if you have any 'scrub' policies).

Once the CIMC is setup in stand alone mode you will need to recreate items like your boot order, vnics.

I would take note of the mac addresses assigned to your current vnics, so you can re-assign the same ones when recreating the vnics in standalone mode.

Your installed OS may take some juggling of the detected NICs/macs.

Dear Kirk,

Thank you for your response. The current scrub policy for disk is disabled.

Can you please clarify on this point "Once the CIMC is setup in stand alone mode you will need to recreate items like your boot order, vnics" ? How can I achieve this? I have pasted the config below.
