Big Bang Migration

n., v.

Pronunciation

/bɪg bæŋ maɪˈgreɪʃən/

Definition

1. A type of data migration in which the data is moved over to the new PIM system in a single instance.
2. The process of moving data over to the new PIM system all at once.

With big bang migration, the data is redirected into the new system all at once. Whenever this option is chosen, a business risks lurching to a halt due to the simultaneous manifestation of all previously unidentified data or system issues. Despite this danger, businesses often prefer big bang migrations as they are less expensive and the urgency of these issues means that they will be quickly resolved rather than put on a backburner.
