+# SLMM Archive
+
+This directory contains legacy scripts that are no longer needed for normal operation but are preserved for reference.
+
+## Legacy Migrations (`legacy_migrations/`)
+
+These migration scripts were used during SLMM development (v0.1.x) to incrementally add database fields. They are **no longer needed** because:
+
+1. **Fresh databases** get the complete schema automatically from `app/models.py`
+2. **Existing databases** should already have these fields from previous runs
+3. **Current migration** is `migrate_add_polling_fields.py` (v0.2.0) in the parent directory
+
+### Archived Migration Files
+
+- `migrate_add_counter.py` - Added `counter` field to NL43Status
+- `migrate_add_measurement_start_time.py` - Added `measurement_start_time` field
+- `migrate_add_ftp_port.py` - Added `ftp_port` field to NL43Config
+- `migrate_field_names.py` - Renamed fields for consistency (one-time fix)
+- `migrate_revert_field_names.py` - Rollback for the rename migration
+
+**Do not delete** - These provide historical context for database schema evolution.
+
+---
+
+## Legacy Tools
+
+### `nl43_dod_poll.py`
+
+Manual polling script that queries a single NL-43 device for DOD (Device On-Demand) data.
+
+**Status**: Replaced by background polling system in v0.2.0
+
+**Why archived**:
+- Background poller (`app/background_poller.py`) now handles continuous polling automatically
+- No need for manual polling scripts
+- Kept for reference in case manual querying is needed for debugging
+
+**How to use** (if needed):
+```bash
+cd /home/serversdown/tmi/slmm/archive
+python3 nl43_dod_poll.py <host> <port> <unit_id>
+```
+
+---
+
+## Active Scripts (Still in Parent Directory)
+
+These scripts are **actively used** and documented in the main README:
+
+### Migrations
+- `migrate_add_polling_fields.py` - **v0.2.0 migration** - Adds background polling fields
+- `migrate_add_ftp_credentials.py` - **Legacy FTP migration** - Adds FTP auth fields
+
+### Testing
+- `test_polling.sh` - Comprehensive test suite for background polling features
+- `test_settings_endpoint.py` - Tests device settings API
+- `test_sleep_mode_auto_disable.py` - Tests automatic sleep mode handling
+
+### Utilities
+- `set_ftp_credentials.py` - Command-line tool to set FTP credentials for a device
+
+---
+
+## Version History
+
+- **v0.2.0** (2026-01-15) - Background polling system added, manual polling scripts archived
+- **v0.1.0** (2025-12-XX) - Initial release with incremental migrations
