Post-migration old wiki notice (From 28/09/2013 to 01/04/2014)

You are visiting an archived read-only version of Wikimedia UK's website. This wiki was formerly hosted by the Wikimedia Foundation before being migrated to Wikimedia UK's server hosting in September 2013. Following migration the site url changed from http://uk.wikimedia.org to http://wiki.wikimedia.org.uk and this is where the current, editable version of the site is available. We have recreated 'stub-accounts' on the migrated site. To receive your new password, please activate "Enable email from other users" in your user profile on this site and the password for your account on the new site will be emailed to you overnight.

Wikimedia UK's wiki migration notice

Message

Dear contributor

Since its creation, Wikimedia UK's wiki has been hosted by the Wikimedia Foundation. The hosting for this site was migrated from the Foundation's datacenter to the Wikimedia UK's over the last week-end of September (28-29th September). It was not possible to migrate non-public account information. This includes watch lists, account preferences, contact email, or current password for registered users.

We have recreated 'stub-accounts' on the migrated site and want to communicate to you your new password:

  • user: <accountname>
  • password: <accountpassword>

Please log in soon at possible: http://wiki.wikimedia.org.uk/w/index.php?title=Special:UserLogin

When you have logged in please change the default password to your personal preference and update your contact email

If you want to know more about this migration: https://wiki.wikimedia.org/wiki/WMUK_wiki_migration

Script (running each night after the migration day)
cat userpasswords | grep Kelson | ./sendNewPasswordToUsers.pl --username=foo --password=bar --host=uk.wikimedia.org --path=w --userCount=1 > userpasswords_next

Known issues

  • The import of logs was partial, only 600 entries out of 60k. (Seems solved now?) Yes check.svg Done Kelson (talk) 12:00, 29 September 2013 (UTC)
  • Special:Contributions is broken (doesn't list old contributions), probably because users were re-created on this wiki with different user_id. Yes check.svg Done Kelson (talk) 12:00, 29 September 2013 (UTC)
  • Special:Log has a fatal (blank page) when crossing this timestamp: [1] (while [2] works) Yes check.svg Done Kelson (talk) 19:23, 30 September 2013 (UTC)
  • Revision IDs change, so oldid/diff links are not compatible with those to the old wiki. Possible "solutions":
    • don't redirect old domain to the new,
    • use an apache redirect to send people accessing those IDs to a warning,
    • redirect to another domain where the old wiki is parked instead.
  • [enhancement] Upon login with the temporary password, user should be forced to change it.
