É preciso realizar um Planejamento Detalhado e Mapear todos os possíveis riscos envolvendo o Plano de Migração. Uma Auditoria abrangente tende a mitigar riscos não mapeados inicialmente e o Backup Completo dos Dados, irá garantir ainda mais segurança visando possíveis Falhas.

When facing a critical network migration, preventing data loss is essential for ensuring a smooth transition. Here are key strategies to mitigate data loss risks: 1. Thorough Planning and Risk Assessment Identify risks: Understand potential risks specific to your network environment, such as data corruption, connectivity issues, or hardware failures. Document the migration process: Develop a step-by-step migration plan that includes rollback procedures if issues arise. 2. Backups and Redundancy Full backup: Perform comprehensive backups of all critical data before starting the migration. Ensure backups are stored both on-site and off-site (cloud or remote storage).

From my perspective for data migration in case of servere network migration first part comes as always as the backup part ensure all points of data is securely backuped along with all configuration files . You can split the data and configuration backup seperately for a extra care and try to restore the configuration backup to the mainframe so that you can test all functionalities are ready to implemented on the new migrated servers or network. Then you can push push old data to servers ensuring a smooth transition on migration. Second part is ensure correct methods for backups are taken to transfer the data. So that no data is missed during migration. Third part as always testing the post migration setup so we can ensure everything good
