 For Redis, we chose to start fresh since it was just cache. If you need to migrate:
 
 ```bash
-# Using redis-cli to export/import
-redis-cli --rdb heroku-redis.rdb
-redis-cli --pipe < heroku-redis.rdb
+# Save RDB snapshot from Heroku Redis
+redis-cli -h <heroku-redis-host> -p <port> -a <password> --rdb heroku-redis.rdb
+
+# On your new server, stop Redis temporarily
+sudo systemctl stop redis
+
+# Replace dump.rdb with your backup
+sudo cp heroku-redis.rdb /var/lib/redis/dump.rdb
+sudo chown redis:redis /var/lib/redis/dump.rdb
+
+# Restart Redis to load the data
+sudo systemctl start redis
 ```
