7. How do you handle data migration when developing applications on ServiceNow?
When developing applications on ServiceNow, data migration is an important part of the process. To ensure a successful data migration, I follow a few key steps.
First, I create a data migration plan. This plan outlines the data that needs to be migrated, the source and destination systems, and the timeline for the migration. This plan helps me to ensure that all data is migrated correctly and on time.
Next, I create a data mapping document. This document outlines the mapping between the source and destination systems. This helps me to ensure that the data is migrated correctly and that no data is lost in the process.
Once the data mapping document is complete, I begin the data migration process. I use the ServiceNow Data Import/Export feature to migrate the data from the source system to the destination system. This feature allows me to easily migrate data from one system to another.
Finally, I perform a data validation process. This process ensures that all data has been migrated correctly and that no data has been lost in the process.
