Actually, changing to high, since it's a current quarterly goal.

Everything seems to be in place, should we schedule this upgrade for March 13th ?

March 13th is a floating holiday for us...maybe shoot for March 14th?

The problem with the 14th is everything would have to be ready in time for the train to roll forward, which seems like too small of a window. We could perhaps do it later this week instead of waiting till monday. Thursday might be reasonable?

@Gehel any thoughts on the 9th vs the 13th for upgrading the codfw cluster to elasticsearch 5?

The 13th has been choosen as the date to start the upgrade.
