After many hours trying to convince the IT director to do this in a off peak time, and with proper planning, he just wouldn't listen to me.
Hyper-V live migration from a HP EVA4400 to a 3PAR Storage.
45 hosts migrated without a hitch. The one that couldn't fail, a SAP production server, failed hard.
The EVA crashed hard, both controllers went offline in the middle of the migration. After a couple of seconds later, one of the PSU's shut off. The other one was waiting for replacement part. My face turned white.
Huge downtime to recover everything from a Tape backup.
A couple of days later, I had a major burn out.

It was a really bad day at work :(
