== Migration Mode Usage ==
** Pre-migration validation and warnings
=== Step 1: Select Disks ===
** Detailed partition information and size calculations
# Insert both source and target SD cards
# Click &quot;Refresh Disks&quot; to detect SD cards
# Select your '''Source SD Card''' (smaller, original)
# Select your '''Target SD Card''' (larger, destination)
 
'''WARNING''': Target disk will be COMPLETELY ERASED!
 
=== Step 2: Scan Source ===
# Click &quot;Scan Source SD Card&quot;
# Wait for the scan to complete
# Review the detected partition layout
 
The tool will automatically detect:
 
* FAT32 partition (hos_data)
* Linux partition (L4T) if present
* Android partitions (Dynamic or Legacy) if present
* emuMMC partitions (Single or Dual) if present
 
=== Step 3: Configure Migration ===

* '''Android Partitions''' (optional)
* '''emuMMC Partitions''' (optional)
 
=== Step 4: Calculate Layout ===
# Click &quot;Calculate New Layout&quot;
# Review the new partition layout
# Check the comparison dialog showing:
#* Source vs Target sizes
#* How much space FAT32 will gain
#* Free space after migration
 
=== Step 5: Start Migration ===
# Click &quot;Start Migration&quot;
# Confirm the warning dialogs
# Wait for migration to complete
 
'''DO NOT''' remove SD cards or power off during migration!
 
Migration Progress:

# Updating emuMMC Config (95-99%)
# Complete (100%)
 
=== Step 6: Verification ===
Once complete:
 
* Safely remove both SD cards
* Insert target SD card into your Nintendo Switch
* Boot normally - all data and partitions preserved
 
== Cleanup Mode Usage ==
=== Step 1: Select SD Card ===
# Insert the SD card you want to clean up
# Click &quot;Refresh Disks&quot; to detect SD cards
# Select the SD card
 
=== Step 2: Scan SD Card ===
# Click &quot;Scan SD Card&quot;
# Wait for the scan to complete
# Review the detected partition layout
 
=== Step 3: Select Partitions to Remove ===
Choose what to remove:
 
* '''Remove Linux''' - Delete Linux (L4T) partition
* '''Remove Android''' - Delete all Android partitions
* '''Remove emuMMC''' - Delete emuMMC partition(s)
 
'''⚠️ WARNING''': Selected partitions will be PERMANENTLY DELETED!
 
=== Step 4: Review Cleanup Preview ===
# Click &quot;Calculate Preview&quot; (happens automatically)
# Review the &quot;After Cleanup&quot; layout
# Verify FAT32 expansion size
 
=== Step 5: Start Cleanup ===
# '''IMPORTANT''': Make sure you have a backup of your SD card!
# Click &quot;Start Cleanup&quot;
# Confirm the warning dialogs
# Wait for cleanup to complete (10-30 minutes)
 
'''DO NOT''' remove SD card during cleanup!
 
Cleanup Process:
 
# Backing up FAT32 data (5-35%)
# Cleaning disk (40-45%)
# Writing new partition table (50-55%)
# Creating FAT32 filesystem (60-70%)
# Restoring FAT32 data (75-95%)
# Updating configs (97-99%)
# Complete (100%)
 
=== Step 6: Verification ===
Once complete:
 
* Safely remove the SD card
* Insert into your Nintendo Switch
* Boot normally - unwanted partitions removed, FAT32 expanded

[GPT] Entry 0: hos_data (FAT32)
== Media ==
[GPT] Entry 1: l4t (Linux)
[GPT] Entry 2-8: Android partitions (boot, recovery, dtb, misc, cache, super, userdata)
[GPT] Entry 9: emummc
[GPT] Entry 10: emummc2</pre>
 
== Important Notes ==
=== Before Migration ===
* Backup your SD card data (recommended)
* Ensure target SD card is '''larger''' than source
* Use a good quality SD card for target
* Close all programs accessing the SD cards
* Run as Administrator
 
=== During Migration ===
* '''DO NOT''' remove SD cards
* '''DO NOT''' power off your computer
* '''DO NOT''' cancel the migration
* Wait patiently (30-60 minutes for 128GB, longer for larger cards)
 
=== After Migration ===
* Verify partition layout in the tool
* Test target SD card in Nintendo Switch
* Keep source SD card as backup until verified working

[[image:NXMigratorProSwitch.png|800px]]
 
== Troubleshooting ==
=== &quot;Administrator Required&quot; Error ===
* Run as Administrator (right-click → Run as Administrator)
=== &quot;No SD Cards Found&quot; ===
* Make sure SD cards are properly inserted
* Click &quot;Refresh Disks&quot;
* Try different USB ports
* Check Device Manager for SD card readers
 
=== &quot;Target disk must be larger&quot; ===
* Ensure target SD card is actually larger than source
* Some SD cards report slightly different sizes
 
=== Migration Fails ===
* Check SD card connections
* Try different SD card reader
* Verify target SD card is not write-protected
* Check for bad sectors on target SD card
 
=== emuMMC Not Working After Migration/Cleanup ===
* The tool automatically updates emuMMC sector offsets in the <code>raw_based</code> files
* If issues persist, verify the emuMMC/RAW1 or emuMMC/RAW2 folders contain correct offsets
* Check nx''migrator_pro''*.log for any emuMMC update errors
 
=== Cleanup Mode Specific Issues ===
'''&quot;Temporary backup directory full&quot;'''
 
* Cleanup mode backs up FAT32 data to your system temp folder
* Ensure you have enough free space on your system drive (C:)
* Required space = size of your FAT32 partition
* Alternative: Free up space on C: drive before cleanup
 
'''&quot;Cleanup failed during restore&quot;'''
 
* If cleanup fails during FAT32 restore, your temp backup is still safe
* Check temp folder (C:\Users\YourName\AppData\Local\Temp\nx''partition_backup''*)
* Manually copy files back if needed
* Always keep original SD backup before cleanup!
 
== Technical Details ==
=== Partition Table Compatibility ===
* Creates '''100% hekate-compatible''' partition tables
* MBR for simple layouts (no Android)
* MBR + GPT for complex layouts (with Android)
* Exact same structure as hekate's partition manager
* 16MB alignment for optimal SD card performance
 
=== Android Partition Schemes ===
'''Dynamic (Android 10+):''' 7 partitions


* boot (64MB), recovery (64MB), dtb (1MB), misc (3MB)
== Changelog ==
* cache (60MB), super (5922MB), userdata (variable)
'''1.0.0'''
 
* Initial Release.
'''Legacy (Android 7-9):''' 9 partitions
 
* vendor (1GB), APP (3GB), LNX (32MB), SOS (64MB)
* DTB (1MB), MDA (16MB), CAC (700MB), MSC (3MB), UDA (variable)
 
== Performance ==
Migration speed depends on SD card quality and reader:
 
* '''Average''': 30-50 MB/s transfer rate
* '''128GB card''': ~45-60 minutes
* '''256GB card''': ~90-120 minutes
* '''512GB card''': ~3-4 hours
 
Performance optimizations:
 
* 32MB chunk size for optimal throughput
* Direct sector-level I/O bypassing filesystem overhead
* Parallel operations where possible
 
==Changelog==  
'''v1.0'''
* First Release.
