Ionic 2 BETA run help

I recently received an Ionic 2 BETA source code from a client who wants me to work on it.
However the source code is different in that there’s no “src” folder, the “app” folder meant to be in “src” folder is in the root folder and there’s no “app.module.ts” among a few others.
I noticed this was a beta version of Ionic 2 so what I’m asking is if there’s a way to still run this project, are those files missing or is this how it was structured at this stage back then?
I’m guessing I may need to update a few system tools, if so which ones?

Package.json:
“ionic-angular”: “2.0.0-beta.10"
@angular/core": “2.0.0-rc.3”

Thanks.

Things were very different back then, one of them being the file structure.

You can read the ionic changelog back from that time to see what changed from version to version. Updating this app might be quite some work. Think about if it isn’t easier to start a new project and just port the functionality bit by bit instead of really going the “update” route.

Thanks Sujan12, I already suggested upgrading however it always comes down to budget.
I went back to some questions on SO and found that Ionic cli beta 31 works well for this particular project.
