+h2. Workbench
+
+The legacy workbench configuration is stored in @config/application.yml@ and @config/database.yml@. After migration to @/etc/arvados/config.yml@, both of these files should be moved out of the way and/or deleted.
+
+Change to the workbench server directory and use the following commands:
+
+<pre>
+$ bundle exec rake config:migrate > config.yml
+$ cp config.yml /etc/arvados/config.yml
+</pre>
+
+This will print the contents of @config.yml@ after merging with legacy @application.yml@. It may then be redirected to a file and copied to @/etc/arvados/config.yml@.
+
+If you wish to update @config.yml@ configuration by hand, or check that everything has been migrated, use @config:diff@ to print configuration items that differ between @application.yml@ and the system @config.yml@.
+
+<pre>
+$ bundle exec rake config:diff
+</pre>
+
+This command will also report if no migrations are required.
