**Proposed migration plans following #OSGeo-sac meeting 2018-03-29**

Martin noted that the current MediaWiki instance is somewhat out of date,
therefore I propose the following migration to both a newer mediawiki
version and ldap authenticated accounts:

1. Setup clean new MediaWiki instance, including all necessary extensions.
2. Export database from current instance and import to new instance.
3. Rename all existing user accounts with prefix, such as "_wikiuser_".
4. Disable login to any account having the prefix.
5. Force all logins through OSGeo LDAP authentication.
6. On first login of a LDAP user to the wiki, prompt user to provide
credentials for any existing wiki accounts they wish to merge; prepend
prefix to authenticate and merge if valid.

We will want to do this on a testing basis first to work out any issues,
then freeze the existing instance before importing clean with a fresh dump
and swapping in the new instance.
