=== 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
+
# After TTL, verify that RT is working on the new server
+
 
+
=== Migration plan - D-Day ===
+
# Notify users.
+
# Make all user data and projects read-only. Verify.
+
# Run scripts to copy user accounts and home directories. Verify.
+
# Run scripts to copy darcs repos, project data, and Trac project. Verify.
+
# Move the domain CNAME for community, trac, projects, and code.
+
# After TTL, verify remotely that the domains moved and that services are working.
+
# Notify users of current status.
+
# Run the scripts to copy mailman lists. Verify.
+
# Tell Ian and Malcolm to check their mail.
+
# Move the domain MX records.
+
# Run the scripts to copy Planet Haskell. Verify.
+
# Move the planet domain.
+
# After TTL, verify remotely that '''all''' domains are moved and that '''all''' services are working.
+
# Notify users and community.
+
 
+
=== Post-migration tasks ===
+
# Monitor and tune settings of PostgreSQL for resource usage on the new server
+
# Monitor and tune settings of Apache for resource usage on the new server
