+# Data Migration Procedure
+## From Jupiter (172.16.3.20) to RMM (172.16.3.30)
+
+**Date:** 2026-01-17
+**Data to Migrate:** 68 conversation contexts + any credentials/other data
+**Estimated Time:** 5 minutes
+
+---
+
+## Step 1: Export Data from Jupiter
+
+**Open PuTTY and connect to Jupiter (172.16.3.20)**
+
+```bash
+# Export all data (structure already exists on RMM, just need INSERT statements)
+docker exec mariadb mysqldump \
+  -u claudetools \
+  -pCT_e8fcd5a3952030a79ed6debae6c954ed \
+  --no-create-info \
+  --skip-add-drop-table \
+  --insert-ignore \
+  --complete-insert \
+  claudetools > /tmp/claudetools_data_export.sql
+
+# Check what was exported
+echo "=== Export Summary ==="
+wc -l /tmp/claudetools_data_export.sql
+grep "^INSERT INTO" /tmp/claudetools_data_export.sql | sed 's/INSERT INTO `\([^`]*\)`.*/\1/' | sort | uniq -c
+```
+
+**Expected output:**
+```
+  68 conversation_contexts
+  (and possibly credentials, clients, machines, etc.)
+```
+
+---
+
+## Step 2: Copy to RMM Server
+
+**Still on Jupiter:**
+
+```bash
+# Copy export file to RMM server
+scp /tmp/claudetools_data_export.sql guru@172.16.3.30:/tmp/
+
+# Verify copy
+ssh guru@172.16.3.30 "ls -lh /tmp/claudetools_data_export.sql"
+```
+
+---
+
+## Step 3: Import into RMM Database
+
+**Open another PuTTY session and connect to RMM (172.16.3.30)**
+
+```bash
+# Import the data
+mysql -u claudetools \
+  -pCT_e8fcd5a3952030a79ed6debae6c954ed \
+  -D claudetools < /tmp/claudetools_data_export.sql
+
+# Check for errors
+echo $?
+# If output is 0, import was successful
+```
+
+---
+
+## Step 4: Verify Migration
+
+**Still on RMM (172.16.3.30):**
+
+```bash
+# Check record counts
+mysql -u claudetools \
+  -pCT_e8fcd5a3952030a79ed6debae6c954ed \
+  -D claudetools \
+  -e "SELECT TABLE_NAME, TABLE_ROWS
+      FROM information_schema.TABLES
+      WHERE TABLE_SCHEMA = 'claudetools'
+      AND TABLE_ROWS > 0
+      ORDER BY TABLE_ROWS DESC;"
+```
+
+**Expected output:**
+```
+TABLE_NAME                  TABLE_ROWS
+conversation_contexts       68
+credentials                 (if any)
+clients                     (if any)
+machines                    (if any)
+... etc ...
+```
+
+---
+
+## Step 5: Test API Access
+
+**From Windows:**
+
+```bash
+# Test context recall
+curl -s http://172.16.3.30:8001/api/conversation-contexts?limit=5 | python -m json.tool
+
+# Expected: Should return 5 conversation contexts
+```
+
+---
+
+## Step 6: Cleanup
+
+**On Jupiter (172.16.3.20):**
+```bash
+# Remove temporary export file
+rm /tmp/claudetools_data_export.sql
+```
+
+**On RMM (172.16.3.30):**
+```bash
+# Remove temporary import file
+rm /tmp/claudetools_data_export.sql
+```
+
+---
+
+## Quick Single-Command Version
+
+If you want to do it all in one go, run this from Jupiter:
+
+```bash
+# On Jupiter - Export, copy, and import in one command
+docker exec mariadb mysqldump \
+  -u claudetools \
+  -pCT_e8fcd5a3952030a79ed6debae6c954ed \
+  --no-create-info \
+  --skip-add-drop-table \
+  --insert-ignore \
+  --complete-insert \
+  claudetools | \
+ssh guru@172.16.3.30 "mysql -u claudetools -pCT_e8fcd5a3952030a79ed6debae6c954ed -D claudetools"
+```
+
+Then verify on RMM:
+```bash
+mysql -u claudetools -pCT_e8fcd5a3952030a79ed6debae6c954ed -D claudetools \
+  -e "SELECT COUNT(*) FROM conversation_contexts;"
+```
+
+---
+
+## Troubleshooting
+
+### Issue: "Table doesn't exist"
+**Solution:** Schema wasn't created on RMM - run schema creation first
+
+### Issue: Duplicate key errors
+**Solution:** Using `--insert-ignore` should skip duplicates automatically
+
+### Issue: Foreign key constraint errors
+**Solution:** Temporarily disable foreign key checks:
+```sql
+SET FOREIGN_KEY_CHECKS=0;
+-- import data
+SET FOREIGN_KEY_CHECKS=1;
+```
+
+### Issue: Character encoding errors
+**Solution:** Database should already be utf8mb4, but if needed:
+```bash
+mysqldump --default-character-set=utf8mb4 ...
+mysql --default-character-set=utf8mb4 ...
+```
+
+---
+
+## After Migration
+
+1. **Update documentation** - Note that 172.16.3.30 is now the primary database
+2. **Test context recall** - Verify hooks can read the migrated contexts
+3. **Backup old database** - Keep Jupiter database as backup for now
+4. **Monitor new database** - Watch for any issues with migrated data

+## Verification Checklist
+
+- [ ] Exported data from Jupiter (172.16.3.20)
+- [ ] Copied export to RMM (172.16.3.30)
+- [ ] Imported into RMM database
+- [ ] Verified record counts match
+- [ ] Tested API can access data
+- [ ] Tested context recall works
+- [ ] Cleaned up temporary files
+
+---
+
+**Status:** Ready to execute
+**Risk Level:** Low (original data remains on Jupiter)
+**Rollback:** If issues occur, just point clients back to 172.16.3.20
