how to convert Ruby application 1.8.7 to 1.9.2

Question

hi I have one application in ruby but in that application developed in ruby 1.8.7, now I am using ruby 1.9.2 any possibility to change my application 1.8.2 to 1.9.2 or 1.9.3

Answer 1

Given that your rails app is using day-to-day ruby functions, upgrading to ruby 1.9 should not be an issue, however read this major changes note, from ruby 1.8 to 1.9.x and see if you are using any methods that are mentioned there. But practically in most cases your rails app should run without any modifications.

And when you are installing ruby1.9.x use RVM (Ruby Version Manager) , to have your both ruby 1.8.7 and 1.9 versions side-by-side.

and if you have a good test suite, this should not be a problem at all :)

best of luck
