Like the DO comment explains, it is not possible to resize your droplet to a lower state. What you could do is

• Create a new droplet
• Backup data from old droplet
• Move data from old –> new droplet over private DO network

Let me know if this helps you, or got any more questions.

Hello, @boryskindenko

I will recommend you to check our official documentation for considerations when Downsizing to a Smaller Droplet: https://www.digitalocean.com/docs/droplets/resources/downsize/

The steps are the one that ForYourIT mentioned. You need to create a new droplet and also backup your data from your old droplet and then migrate the files from the original backup to the new one. The migratio process is fairly simple and I can recommend you to use rsync in order to achieve this.

Hope this helps! Let me know if you have any questions about the process.
