Hello and welcome to the latest edition of the WMF Roadmap and Deployments update.

See the full roadmap for next week and beyond here: https://wikitech.wikimedia.org/wiki/Deployments#Week_of_March_3rd

Some important call outs:

== Monday ==

The migration of WMF Labs from pmtpa to eqiad begins * new instance creation disabled in pmtpa, only available in eqiad * See the emails from Andrew and Marc for more details: ** http://lists.wikimedia.org/pipermail/labs-l/2014-February/002152.html ** http://lists.wikimedia.org/pipermail/labs-l/2014-February/002153.html

We will be disabling ArticleFeedBack on all wikis. * https://bugzilla.wikimedia.org/show_bug.cgi?id=61163

== Tuesday ==

MediaWiki upgrades * group1 to 1.23wmf16: All non-Wikipedia sites (Wiktionary, Wikisource, Wikinews, Wikibooks, Wikiquote, Wikiversity, and a few other sites) * see also: ** https://www.mediawiki.org/wiki/MediaWiki_1.23/Roadmap#Schedule_for_the_deplo... ** https://www.mediawiki.org/wiki/MediaWiki_1.23/wmf16

== Wednesday ==

The new search cluster will be upgraded (to ElasticSearch 1.0.1). * This will begin at 0:00 UTC March 6th/4pm Pacific March 5th and will take a few hours to complete. * All wikis currently using the new search (CirrusSearch) will be temporarily switched back to the old serach (lsearchd) * You shouldn't see much of a change in search behavior (CirrusSearch is mostly feature parity to lsearchd) if your wiki is on new search, but to see a list of wikis that currently have CirrusSearch enabled (and in what way: Beta Feature or Primary), see: ** https://www.mediawiki.org/wiki/Search#Wikis

== Thursday ==

MediaWiki upgrades * group2 to 1.23wmf16 (all Wikipedias) * group0 to 1.23wmf17 (test/test2/testwikidata/mediawiki)

As always, questions welcome,

Greg
