Hello, 

To move from one version to another gradually you should take a look at 
Traffic migration. [1]
Note that this is not supported in the App Engine flexible environment.

Re: [google-appengine] Re: Google App Engine - Split Traffic and promote

[Bilal Haidar]

Oh thanks George!

Either I use two services of the same code base one for prod and one for
staging. Or opt for two projects, one for prod and the other for staging?

Then, traffic splitting works against a single service (without the version
specified in the URL). In other words, traffic is split among the versions
of the service and not among two different services.

Is there a way to automate moving from one version to another gradually?

Hello, 

You are right, you can use traffic splitting to specify a percentage 
distribution of traffic across two or more of the versions within a 
service, as detailed on the "Split Traffic" page 
. 
Deploying with --promote would attract all traffic to the deployed version. 
However, by contrast, traffic splitting is applied to URLs that do not 
explicitly target a version. In other words, you'll need 2 separate 
services, one for your prod environment, the other for staging. Two 
versions would not work for traffic splitting. 

You can access different versions by version URLs at any time.
