 I've started working on this.

 Trying to upgrade wiki-staging (a snapshot of production).

 At moment I' running into some issues using

 php composer

 It seems some packages require upgrade using composer 1.0 ( and some
 others required composer 2.0 ( doctrine/dbal)

 I'm still troubleshooting this in stagine and once I've fixed, hopefully
 can do the production upgrade
