Hi @Saravanaprasad_k,
You can simply use the method dropDatabase(), to remove the old database.

above suggestion is about removing from inside. but you may want to clean them all without thinking what to delete :slight_smile: then read ahead.

your old installations seems to use “default” data path that won’t be removed upon uninstallation. usually /data/db, but can be somewhere under /var. it needs manual removal through OS. you should find the config file or that default path for your OS distro, then remove that folder as well. this way, your next re-installation will be clean.

a third option is to change the init file and use different data folders. this requires you to learn some more DB admin concepts. so I will leave it to you.
