Purpose:
Cut building over from UCDNet3 to UCDNet4

Impact:
The cutover will begin during it's turn within the
maintenance window and last about 3 hours. In the beginning
phases of each building cutover, there could be several 1-2
minute outages as edge switch links are converted to use
LACP. This conversion phase could last from 30 to 90
minutes. Once the conversions are complete, Net3 links and
router interfaces will be disabled and a link migration to
Net4 will begin. This could take between 30 to 120 minutes
depending on the size of the building. During this second
phase of the building cutover, the outage experienced could
range from 5 to 120 minutes depending on switch migration
order.
