A runbook is a step-by-step guide that describes all procedures and operations that must be considered or addressed during the cutover.
A runbook contains all the required documentation for each member of the cutover team to complete their tasks, as well as timelines and detailed instructions so that everyone can work together effectively and efficiently.
To guarantee that there are no problems throughout the cutover process, your deployment runbook will need to be more extensive the larger and more complicated your business' old systems are. Most IT networks today span several systems and include third-party applications, therefore they should all be included in the runbook to avoid or minimize downtime.
