A professional partition management tool for Nintendo Switch SD cards with dual-mode operation: Migration and Cleanup.

NX Migrator Pro provides two powerful modes for managing your Nintendo Switch SD card partitions:

• Migration Mode - Migrate partitions from a smaller SD card to a larger one with automatic FAT32 expansion.
• Cleanup Mode - Remove unwanted partitions (Linux/Android/emuMMC) from a single SD card and reclaim space for FAT32.

System requirements:

• OS: Windows 10/11 (64-bit)
• RAM: 512MB minimum
• Permissions: Administrator privileges required
• Disk Space: Minimal (application is ~10MB)

Hardware requirements:

• Source SD Card (your current smaller card)
• Target SD Card (must be larger than source)
• SD card reader(s) - can use one or two readers

  • Auto-Expand FAT32 - Automatically expand FAT32 to use free space
