Maintaining jquery.min.js files in Rails assets path -

i have rails application built in rails 3.0.3 , ruby 1.8.7. upgrading same rails 3.1.3 , ruby 2.0.0-p247. while configuring assets, have used jquery-rails gem inside gemfile include jquery files. see files jquery.js , jquery.min.js installed , served through asset pipeline. version of jquery library jquery javascript library v1.10.2

the problem had several versions of jquery.min.js in rails 3.0.3 application jquery-1.4.2.min.js, jquery-1.4.4.js, jquery-1.9.1.min.js. whether need maintain these files if having updated 1 in app (jquery javascript library v1.10.2) ?

hope can me out :)-

if use asset pipeline should check manifest file , see jquery file included.

if have there

//= require jquery 

but there no file jquery.js in folders, means file provided jquery-rails gem. can safely remove other jquery files.

see jquery-rails gem.
