Create Migration Plan + +Plan to free up a disk (e.g., disk_d) by moving files to other disks: + +```bash +python src/main.py plan disk_d disk_e disk_f +``` + +This creates a JSON file: `migration_plan_disk_d_YYYYMMDD_HHMMSS.json` + +**Review the plan carefully before executing!** + +### 3. Execute Migration (DRY RUN first!) + +**ALWAYS test with dry-run first:** + +```bash +python src/main.py execute migration_plan_disk_d_20231209_143052.json --dry-run +``` + +**Dynamic Output Example:** +``` +[1523/5000] 1520 OK, 3 ERR | 12.3 files/s | ETA: 283s | Documents\project\file.txt +``` + +**If dry-run looks good, execute for real:** + +```bash +python src/main.py execute migration_plan_disk_d_20231209_143052.json +``` + +⚠️ **WARNING**: This will copy files.
