Upgrade java code to 1.7 version
Hi I am software architect and I have such issue.
One task in my project is to upgrade one Java module from 1.4 to 1.7 and change the operating system from Windows to Linux Redhat. What would be your estimation of such task? Is it simply upgrade JDK and system reinstalation or should I assume that developers should redevelop some (or even whole ) code?
Thank you in advance
Darek

How on earth would you expect us to estimate anything about a job that we have no context about?
Honestly, if this is the type of question you're asking, you've bitten off more than you can chew and should tell your managers immediately. I'm not trying to be cruel, but it's better to admit it now than later.

Kevin, I not expect that you or someone else tell me that this is exactly 2 FTE or something like that. I rather was wonder if there is simply programming job or we need to rewrite code of this module. As far as I understood this is the second case.
Thanks for your quick reply.
Re: Upgrade java code to 1.7 version
It really depends on the code. For a simple Hello World, code written for 1.4 should work fine everywhere. But for more involved code using native libraries, or if you want to upgrade to using things like generics, then that's going to involve some coding. How much of an effort that is really depends on the context, which only you have. It could take anywhere from a few minutes to several years, depending on the scope of the project you're talking about. We have no way of judging that without knowing a lot more about your context, and that's not something you're going to be able to convey over a forum. That's why I say that if you really have no idea how to approach answering the question, you've bitten off more than you should be trying to chew right now.

Re: Upgrade java code to 1.7 version
clear, of course this is not a trivial module and detailed estimates and forum is not the place for such considerations. I needed to quickly figure out what is the scale of the problem. I'm not a Java expert and I do not pretend that I am.I just ask Java SME to estimate workforce. From the other side, based on functionality or maybe number of kLOC I will estimate as if we were doing this module from scratch. Those two number will be basis for further decision in project.
