Which practice is recommended when migrating data to multiple ServiceNow instances?

• A. Import to all instances at once
• B. Import to each instance separately
• C. Do not migrate to multiple instances
• D. Use the same data across all instances

Answer: (B)

When migrating data to multiple ServiceNow instances, import the data into each instance separately. Each instance is isolated and may have different configurations, data models, and privacy requirements. Migrating separately lets you tailor field mappings, transforms, and referential integrity for each environment, validate the data in every instance, and control timing and sequencing to minimize risk. It also reduces the chance of cross-environment conflicts and makes it easier to scrub or adjust data for different tenants as needed.

Importing all at once forces a single, one-size-fits-all process that may not fit every instance, leading to mapping errors, security or privacy issues, and failed validations. Not migrating across multiple instances or using the same data across all instances without adaptation can lead to incomplete or inappropriate data in some environments.
