Is there anyway in which I can maintain two different ember-cli projects with different versions of ember-cli on my system ?? The use case is that I want to start a new ember app but don’t want to upgrade ember-cli on an already existing one.

Just avoid the globally installed ember-cli and you are fine. For example to build, run the locally installed (project specific version) ember-cli `./node_modules/.bin/ember build`

As @ilkkao said, using the relative path to `./node_modules/.bin./ember` does the trick. I also use [smartcd](https://github.com/cxreg/smartcd) and have a `.bash_enter` file at the root of every ember-cli project that prefixes `./node\_modules/.bin/ to the front of my $PATH.
