Scheduled Service Change: Move Server Farm switches to new feed switches
sfm1-1-3500 will be down for about 5 minutes however sfm2-1-3500 should hide this from users. sfh1 and 2 changes should not be visible to anyone.
There is no workaround for this issue
The switch maintenance is on four switches that are part of a redundant switch configuration that provides access to the central Active Directory and Exchange service. No service outage will occur.
