Planned sequence: 1. (day before) Send email to the wikidata list 2. Take wdq1001 out of varnish config 3. Shut down and reimage wdq1001. Verify disk partitioning is correct. 4. Deploy new code from wdq-deploy repo. Do NOT restart wdq1002 yet! 5. Reload data to wdq1001 from https://dumps.wikimedia.org/wikidatawiki/entities/20160425/ dump ttl-gz version (should be ready by then) 6. Start updater on wdq1001 and wait for it to catch up 7. Re-add wdq1001 to varnish, verify it's ready to serve requests 8. Disable updater or wdq1002 9. Put wdq1002 into maintenance mode (no need to take it out of varnish as we are only reloading data, not reimaging) 10. Reload wdq1002 data from the same dump as above. 11. Re-enable updater on wdq1002 and wait until it catches up 12. Remove maintenance mode from wdq1002 13. Verify everything works fine and queries run on both servers 14. Send the victory email to wikidata 15. PROFIT!
