If FL2 didn't have the outage, and FL1 did, the pace of the migration did have an impact.

Though this is showing the problem with these things: Migrating faster could have reduced the impact of this outage, while increasing the impact of the last outage. Migrating slower could have reduced the impact of the last outage, while increasing the impact of this outage.

This is a hard problem: How fast do you rip old working infrastructure out and risk finding new problems in the new stack, yet, how long do you tolerate shortcomings of the old stack that caused you to build the new stack?
