I ran across this doing the gear size change in sprint 2.0.7 and gear name change in 2.0.8. We'll likely have scalable apps on prod for the next migration. The method of app.gear provides access to the first gear object of an application which should be fine for non-scalable apps. The following will work on both non-scalable and scalable apps. Access all the gears for an app: users = CloudUser.find_all(nil) users.each do |user| user.applications.each do |app| app.group_instances.each do |gi| gi.gears.each do |gear| # Do something with gear end end end end An example for the migrate-mongo script: users = $coll.find() users.each do |user| user["apps"].each do |app| app["group_instances"].each do |gi| gi['gears'].each do |gear| # Do something with gear end end end end
I know move is also broken with multiple gears.
Change is in place for migrate-2.0.10
