XCode toolchain: how to move an App from one accounts to another?

Question

Similar to this situation [*].

Follow up clarification please, as I'm in a parallel universe:

• A. Me, as single Apple Developer.

and

• B. Client, with team of two - I was just added as person 2, an Admin

  (NOT the Agent - he's person 1).

Client gives me source code for an * App rewrite/fix. * First version is still live on App store, my upgrade is to be its replacement.

I did the App rewrite on my machine, using my Apple dev account and my developer certs for device testing. So, at this point, it appears to be "my" app. Note, I do not yet have distribution nor iTunes Connect for me OR client. But THEY do have them for the earlier release of the App, which my upgrade is to replace, as mentioned. )

Now, it's bug-free :-/ and needs to go live under the client's account, not mine.

Here's where I'm stuck and befuddled. (I talked with Apple, and they were somewhat helpful, but I'm concerned about corrupting / conflating all the certs / accounts on my machine.)

Questions:

1a. Can Client just use the portal (under their id) to generate new distribution certs / provisions for me to use ?

1b. and I should put those into MY XCODE ?

"2." Then I can distribute under their account ?

3a. Must they also generate (from their account) a developers cert too for me ? (Two people at Apple suggested so, but weren't sure.)

3b. In which case, must I recompile under their dev cert on my machine, before doing their distribution?

This seems almost Rocket Science difficult, but it shouldn't be !

Thanks for any assistance.

( I hope this really does qualify as a programming question according to FAQ item 3 "tool chain" !)

Answer 1

I think you can either share the client's distribution cert or re-generate a new one.

For the latter case, the client can't distribute the app anymore. You can google it for the first solution, there are heaps.
