I have always fantasized that one day I wouldn't have to stay up til 10pm on Sunday to do a deployment.

I came up with an idea but not certain if this will work please advise.

So, what if I have my existing running production instance say on port 8080.

I then setup another JBoss instance and lets call it "Next Deploy" which will be a prod staging environment on port 666.

Once Next Deploy is up ready, tested, and ready to become the production instance to deploy would be simple.

I would simply change Next Deploy to point to port 8080(prod environment) and I change the current existing production server to 111.

Would this work?  Please advise, thanks!
