I have an old ROR app that is running Ruby 1.9.3, Rails 4.2.4, and MongoDB 3.0. I need to move it to Ruby 2.2.2, Rails 4.5, and MongoDB 3.2.

I took over this project so the code is currently running on hosting service. I have downloaded source code. However, I wanted to build a simple scaffold app locally on my machine with the Gem file from the project that needs updating. First, the gem file of the project doesn't list specific versions of the gem, so if I try to use bundler it is trying to grab all the newer versions of the gems. The Gemlock file of the project does contain the version numbers being used.

My question is can I use the contents of the gemlock file (copy + paste) into my local Gem file then run bundler. Will this work properly, meaning will it get the proper gems (the versions being used on the production server)? I understand that some of those gem version might have been removed. Thinking I just comment those out of the gem file then run bundle install until it works.

You don't need to bother about Gemfile.lock file, First you change the version of gems that you need to update in Gemfile which will update Gemfile.lock after bundle update.

e.g Change Gemfile to update rails version

gem 'rails', '4.2.4'

to

gem 'rails', '4.5.0'

And simply bundle update rails this will update rails gem and it's dependencies.

But you want to update only rails without its dependencies(not recommended at least for gems like Rails)

e.g. bundle update --source rails  

Refer bundle update command

PS: You can add ruby version(=2.2.2) in Gemfile which will automatically switch the ruby version if your are using rvm.
