We have a product that has been built using the milia multi-tenanting gem (https://github.com/jekuno/milia) . Unfortunately it seems this gem is dead. We can't upgrade past Rails 5 because of this.
Is there any way to move from milia to another gem (eg apartment https://github.com/influitive/apartment - though I see that hasn't been updated in 2 years either!) and not force everyone to recreate passwords etc?
I ended up modifying Milia to work with Rails 6. That new gem is called Philia
