If your BitTitan runbook mainly explains what the migration is supposed to do, you may have a reference document but not the operational guide your team needs when something breaks.

A runbook that only outlines the planned sequence helps on paper. A runbook that also captures decision points, failure thresholds, rollback conditions, and escalation routes becomes the tool the team can execute under pressure. That difference becomes very real at 2 AM when throughput drops and someone has to decide whether to keep going or stop.

In a live cutover, the runbook sections that matter most are: a pre-cutover validation checklist with pass and fail criteria, a job submission sequence with expected timing by batch, throughput monitoring thresholds that trigger escalation, common failure scenarios paired with response steps, rollback decision criteria with explicit triggers for a rollback discussion, the BitTitan support escalation contact path, and a post-cutover validation checklist.

Across acquisition migrations, the runbook was what kept a 10-plus engineer team aligned during the window. When throughput dipped, it clearly stated which engineer owned which diagnostic check, along with what decisions could be made independently versus what required escalation.

Does your runbook spell out what the team does when things go wrong, rather than only describing what the migration does when everything goes right?
