What is an essential step to take before migrating data to Google Workspace from other platforms?

Performing a thorough backup of existing data is crucial before migrating to Google Workspace. This step ensures that you have a complete copy of all important information stored on the original platform, safeguarding against data loss during the migration process. Data migrations can sometimes result in unintended consequences, such as data corruption, transfer errors, or loss due to compatibility issues. By backing up existing data, you secure a fallback option, allowing for recovery should something go wrong during the migration.

Other options provided, such as deleting old archives or enabling third-party applications, do not directly contribute to the integrity and security of the data being migrated. Notifying users about changes to their email addresses can be important for communication but does not address the primary concern of ensuring data safety.
