It will be a true story.
Yes, I've worked from 0900 till 0400. Is the clock running backwards? Nope.
What I can recall now on that moment was like, we in war. Phone kept ringing and people walking around faster than usual (minus the shouting and gun pointing). Things and instruction steps got messed up. The rehearsal we've gone through before the go-live and the real go-live itself was having too many environment changes.
- Our user privilege were not there. We can't update the setting unless we call the DBA for help.
- New data or non related to migration causing interruption. Client can do whatever they want. (On migration go-live? Seriously, what are they thinking?)
- Plan/Instruction steps were jumble up. Due to point 2.
Update: I'm totally defeated when I heard one of my colleague only slept one hour. Not a good sign for the project and I hope this doesn't affect her health.
