how to switch ifgrp ports from 1Gb to 10Gb in 9.1 ?

Hi

Is there a recommended procedure to switch the ifgrp ports from 1Gb to 10Gb in ONTAP 9.1 ?

In the olden days of 7-mode it was a relatively simple procedure edit rc files and failover the nodes etc.

Not sure how to approach this in ONTAP 9.1.

The cluster nodes currently have multimode lacp ifgrp's with 2x1Gb ports each.    We are introducing 10Gb infrastructure at that site and want to switch the ifgrp's over to the 10Gb ports.

Thanks
