Migration from Attic

This guide explains how to migrate from Attic to Celler.

Migration Guide

Caution

The migration process is not regularly tested. Use at your own risk and please backup your database before proceeding.

Note

The Celler server’s API is deliberately not compatible with the Attic CLI tool. Use the Celler CLI instead.

Step 0: Backup Your Database

Before proceeding, make sure to backup your database.

Step 1: Adapt Server Configuration

Adapt your NixOS configuration to use Celler instead of Attic:

  • Point your Flake input to github:blitz/celler.
  • Rename services.atticd to services.cellerd.

Step 2: Adapt Client Configuration

Client configuration needs to be adapted as well.

  • Point your Flake input to github:blitz/celler.
  • Replace the attic package with celler in your client configuration.
