want to migrate our rails application from the older 1.1.6 version to  
the latest released version, Can anyone please give me instructions in  
doing so, is this migration feasible or not, Please tell me  
disadvantages also.

Thanks & Regards

You may find it easier to move to 1.2.x first, fix all the deprecation  
warnings and then move to 2.0.x

Hi fred,  
Thank you for your reply, I think there is only some difference in  
between rails 1.1.6 and 1.2. But is there any possibility converting the  
whole project by writing a script?

Any way if you know any site where I can find all the difference between  
the versions, I will try to write a script to change the project from  
one version to another

thanks and regards  
Raju

Not that I know of. Someone once wrote a script to warn you of all the  
deprecated things you might be using but you still have to go ahead  
and fix it yourself.
