Technical Details

Service Type: Production

Server Name: bdds-its-seb-1, bdds-its-cool-1.umnet.umich.edu

Comments:
Move DHCP subnets for the ITS buildings (ASB, Boyer, and Arbor Lakes) from adonis1,2,7,8 to:
bdds-its-cool-1
bdds-its-seb-1
The purpose is, after lab testing, to pilot any new changes on this pair of servers first, then update the other production BlueCat servers.
DHCP servers are in failover pairs. One of each pair will be moved at a time, so there should be no outage.

2018-05-21 Postponed one week.

2018-06-01 Postponing a week, could not verify the logs yet due to logging updates.

2018-06-07 Postponing another week for more verification.

2018-06-24 most subnets were moved. A few had issues and were moved back until that can be fixed. Will keep change open for another week.

2018-06-25 The remaining subnets will be done one by one in coordination with the owner, or next weekend in CHG0059592
