Transfer vaultwarden with its data to a new server

[chraebsli]

Hello everyone

Some time ago, I made a Vaultwarden installation on my personal VPS server. For a moment, I only used it for testing and some personal passwords, but meanwhile I have many users on this instance. These users are not only friends and family, but also some clients.

Now I need to "reinstall" the server in a cleaner environment and on another server (not existing yet), but with all data (passwords, sends, files, accounts, organizations, ...).

I plan to use a VPS with Ubuntu again, but this time a clean install which is easy to update, maintain and backup.

Is it even possible to transfer all the data to a new server? Do you have some recommendations about which database to use or which not? any other tips?

I'm aware that undocumented installations without backups in a production environment are the opposite of what should be done, but I only wanted to test out Vaultwarden and somehow completely forgot that this is a messy install
