I have v.14 with my custom app installed in a server. Now how can I upgrade it to v.15 without losing any data?

You have two options to upgrade from v14 to v15.

Option 1 is to first upgrade v14 to the latest version of itself. After that, take a complete backup of your data and files. Then, you can set up a new v15 version bench, install the necessary app and install your backup there. This way, you can test v15 without losing anything from your current setup.

Option 2 is to back up your data first and then directly upgrade from v14 to v15. This method skips the step of upgrading v14 separately.

This command directly upgrades your ERPNext from v14 to v15 in the same bench after you’ve taken a backup. Just remember to run migrations afterward to apply any necessary changes to your database.
