User blog comment:MisterWoodhouse/The first migrations to the Unified Community Platform/@comment-45506666-20200526181619/@comment-24006128-20200526183111

The reason we're staging the migrations is so that communities have access to tools they need to thrive. Not all wikis need the most complex extensions, so being able to migrate some of those wikis earlier and letting them take advantage of mobile editing, new core tools from the Wikimedia Foundation, faster performance, etc. is beneficial not only for them, but also for us so that we can better understand how the platform performs and what changes we can make to improve it even further.
