| - | === Migration plan - preparatory stage ===
| + | |
| - | # Formulate plan on how to communicate with users during the migration process; begin gathering required contact info if necessary
| + | |
| - | # Give preliminary notice to users and ask for feedback
| + | |
| - | # Configure domain name etch.haskell.org (will later become read-only copy and left active for a while as a backup)
| + | |
| - | # Set up an IRC channel for admins to coordinate during the migration process
| + | |
| - | # Change TTL on all domains to be short
| + | |
| - | # Provision the new server
| + | |
| - | # Install and perform basic configuration of all services
| + | |
| - | # Test all installed services
| + | |
| - | # Write scripts to copy user accounts and home directories, and to verify
| + | |
| - | # Write scripts to copy project groups in /etc/group, and to verify
| + | |
| - | # Write scripts to copy darcs repos from /srv/projects, and to verify
| + | |
| - | # Write scripts to copy project data from /srv/code, and to verify
| + | |
| - | # Write scripts to copy trac projects, and to verify
| + | |
| - | # Write scripts to copy mailman lists, and to verify
| + | |
| - | # Write scripts to copy Planet Haskell, and to verify
| + | |
| - | # Write a script to make all user data and projects read-only, and to verify.
| + | |
| - | # Write a script to *undo* making things read-only, in case of emergency.
| + | |
| - | # Test all scripts thoroughly
| + | |
| - | # Fix a date for migration and give advance notice and instructions to users.
| + | |
| - | # Transfer RT database and verify (as a dry run, go through the entire migration process just for RT)
| + | |
| - | # Move the rt domain
| + | |

| + | |
