由人工智能和领英社区提供技术支持

Migrating your operating system (OS) can be a daunting task, especially if you have a lot of data and settings to transfer. Whether you are upgrading to a newer version, switching to a different platform, or moving to a new device, you want to make sure you don't lose any important files or configurations. In this article, we will share some tips and tools to help you avoid data loss when migrating your OS.

1 Backup your data

The first and most essential step to avoid data loss is to backup your data before you start the migration process. This means creating a copy of your files, folders, applications, and settings on a separate storage device, such as an external hard drive, a USB flash drive, or a cloud service. You can use the built-in backup features of your current OS, such as Windows Backup and Restore or Time Machine for Mac, or third-party software that can perform full or incremental backups. A backup will allow you to restore your data in case something goes wrong during the migration or if you are not satisfied with the results.

Sauvegarder et tester régulièrement les restaurations système pour valider les procédures. Le PRA doit être largement documenté en envisageant tous les cas de figure. Envisager un schéma fonctionnel pour décrire la méthode à adopter en fonction du problème.

2 Choose the right tool

The next step is to choose the right tool to migrate your OS. Depending on your situation, you may need a different type of tool. For example, if you are upgrading to a newer version of the same OS, you can use the update feature of your current OS, such as Windows Update or Software Update for Mac. If you are switching to a different platform, such as from Windows to Linux or vice versa, you can use a tool that can create a bootable media and install the new OS on your device, such as Rufus or UNetbootin. If you are moving to a new device, you can use a tool that can clone your entire disk or partition and transfer it to the new device, such as Clonezilla or EaseUS Todo Backup.

3 Verify the compatibility

The third step is to verify the compatibility of your data and applications with the new OS. Some data formats and applications may not work well or at all on the new OS, so you need to check if they are compatible or if you need to convert them or find alternatives. For example, if you are migrating from Windows to Linux, you may need to convert your NTFS partitions to a Linux file system, such as ext4 or btrfs, or use a tool that can mount NTFS partitions on Linux, such as ntfs-3g. Similarly, if you are migrating from Mac to Windows, you may need to convert your HFS+ partitions to a Windows file system, such as NTFS or FAT32, or use a tool that can mount HFS+ partitions on Windows, such as Paragon HFS+. You can also use online tools or software to convert your documents, images, videos, and other files to compatible formats. For applications, you can check if they have versions for the new OS, or use emulators, virtual machines, or compatibility layers to run them on the new OS.

4 Test the migration

The fourth step is to test the migration before you finalize it. This means booting into the new OS and checking if everything works as expected. You can use a dual-boot or a live boot option to test the new OS without affecting your current OS. You can also use a virtual machine or a sandbox to test the new OS in an isolated environment. Testing the migration will help you identify and fix any issues or errors that may occur, such as missing drivers, broken links, corrupted files, or incompatible settings.

5 Restore your data

The fifth step is to restore your data from your backup to the new OS. This means copying or syncing your files, folders, applications, and settings from your backup device or service to the new OS. You can use the built-in restore features of your backup tool, or manually copy or drag and drop your data. You can also use third-party software that can migrate your data and settings across different platforms, such as Laplink PCmover or Zinstall WinWin. Restoring your data will help you access and use your data and applications on the new OS without losing any functionality or quality.

6 Clean up your old OS

The final step is to clean up your old OS after you are satisfied with the migration. This means deleting or formatting your old OS partition or disk, or uninstalling your old OS from your device. This will free up some space and resources on your device and prevent any conflicts or confusion between the old and the new OS. You can use the disk management or partitioning features of your new OS, or third-party software that can erase or wipe your old OS, such as DBAN or CCleaner. Cleaning up your old OS will help you complete the migration and enjoy the benefits of the new OS.

Le nettoyage ainsi que le décommissionnement des environnements en obsolescence ne doit pas être négligé; bien souvent, il sert de porte de retour en cas de migration problématique, de ce fait, les SI se gardent l'ancien système ou version du logiciel à disposition mais freinent à la mise en place d'une roadmap d'élimination de l'ancien système. Le cas le plus significatif que j'avais rencontré fut une panne électrique suivie d'un reboot automatique des serveurs: quand l'ancien serveur DHCP se mit à diffuser ses pools d'adresses IP sur le réseau, ce fut une grosse collision d'adresses anciennement réservées qui prirent le dessus sur la configuration du moment. Il faut donc se mettre des échéanciers quant au décommissionnements et s'y tenir

To prevent data loss during OS migration, use specialized software like Acronis True Image or EaseUS Todo Backup for comprehensive backups. Cloud platforms like OneDrive or Google Drive offer secure storage for easy access and restoration. Businesses migrate IT infrastructure without data loss, thanks to these solutions, ensuring a smooth transition.

Esto dependerá de lo que quiera: ? Si quiere conservar el sistema operativo, las aplicaciones y los datos, lo recomendable es clonar el disco duro. ? Si quiere migrar a otro sistema operativo, puede utilizar el asistente de migración del sistema, pero este no migrara las aplicaciones instaladas. ? Otra posibilidad es guardar los datos en un disco duro externo y utilizar un instalador automático de aplicaciones en el nuevo sistema. Y antes que surja la pregunta os adjunto los que yo suelo utilizar de instaladores automáticos de aplicaciones: ? Ninite. ? Patch My PC (Actualizador de aplicaciones).
