Anyone have any advice regarding upgrading Wikibase?  We want to upgrade the install at https://para-sports.es/ but there are a bunch of technical hurdles that are difficult to get past.  These include:

1. Upgrading Mediawiki to the latest version in order to be able to upgrade Wikibase.  This needs to be done without changing the local customization settings and while trying to maintain a potential Mediawiki farm, as we want to be able to have a local image thing like Commons that can be pulled into Wikibase where Commons would be.
2. Upgrading extensions to be current with new version of Mediawiki.
3. Upgrading Wikibase after upgrading Mediawiki.  Our database for Wikibase is over 100,000 items,  We don't want to screw this up.
4. Upgrading the query engine after this, and being able to better localize this as the current examples are from Wikidata, and we can't seem to get rid of the Wikidata logo from the Query engine.
5. Installing the OAuth extension.  This is required for Quick statements extension.
6. Installing QuickStatements.
