Purpose: Cut second building from UCDNet to UCDNet4 (Phase 2).

Impact: The cutover will begin at 8:00. In the beginning phases of the 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 by link migration to Net4 will begin. These links are migrated one by one to ensure the links end up in the correct ports on Net4. This could take between 30 to 120 minutes depending on the size of the building.

In general, the whole cutover should take about 3 hours. The late morning and afternoon are reserved for any troubleshooting that may be needed.
