Ubuntu Trusty was released in April 2014, and support for it
(including security updates) will cease in April 2019. We need to shut
down all Trusty hosts before the end of support date to ensure that
Toolforge remains a secure platform. This migration will take several
months because many people still use the Trusty hosts and our users
are working on tools in their spare time.
== Initial timeline ==
Subject to change, see Wikitech[0] for living timeline.
* 2019-01-11: Availability of Debian Stretch grid announced to community
* Week of 2019-02-04: Weekly reminders via email to tool maintainers

* Week of 2019-03-04:
** Daily reminders via email to tool maintainers for tools still
running on Trusty
** Switch
login.tools.wmflabs.org to point to Stretch bastion
* Week of 2019-03-18: Evaluate migration status and formulate plan for
final shutdown of Trusty grid
* Week of 2019-03-25: Shutdown Trusty grid
== What is changing? ==
* New job grid running Son of Grid Engine on Debian Stretch instances
* New limits on concurrent job execution and job submission by a single tool
* New bastion hosts running Debian Stretch with connectivity to the new job grid
* New versions of PHP, Python2, Python3, and other language runtimes
* New versions of various support libraries
== What should I do? ==
The Cloud Services team has created the Toolforge Trusty
deprecation[1] page on
wikitech.wikimedia.org to document basic steps
needed to move webservices, cron jobs, and continuous jobs from the
old Trusty grid to the new Stretch grid. That page also provides more
details on the language runtime and library version changes and will
provide answers to common problems people encounter as we find them.
If the answer to your problem isn't on the wiki, ask for help in the
#wikimedia-cloud IRC channel or file a bug in Phabricator[2].
