Also, We can do these three steps too.

rake db:drop
rake db:create
rake db:migrate

or simply,

rake db:migrate:reset => which runs db:drop db:create db:migrate

As error suggests you have an existing table named admin_users. you may have already attempted an active_admin migration, try resetting your database.

rake db:reset
