I have a migration file like [datetime]_create_posts.rb . Now I want [anotherdatetime]_create_posts.rb with some changes different from older migration that I can run with ... rake db:migrate VERSION=[anotherdatetime]. How can I create [anotherdatetime]_create_posts.rb, which is basically a new version?

you probably don't want to *create* the posts table again, you likely want to change the existing schema. just make a new migration like so: "ruby script/generate migration 'do_something_else_to_posts' " and then use the add_column, remove_column, rename_column, etc... methods for migrations.
