This is what is driving me nuts. For this discussion let me outline all the elements:
1. I have 2 GA Accounts: for this let's call them OLDGA and NEWGA. What I want to do is give NEWGA complete access to all OLDGA Analytics Accounts.
2. I have profiles created for each of the OLDGA Accounts, as I do for the NEWGA accounts.
3. As User Admin in OLDGA, I have given User NEWGA Administrative access to OLDGA (I have also tried simply to give right to view reports without admin access; same problems)
4. I log into NEWGA and look at the droplist of available Analytics Accounts (as you point out, top right). NONE of the OLDGA accounts are listed, only those created under NEWGA.
5. I even tried to add a new profile in NEWGA for one of the domains in OLDGA just to see if that would "prompt" the system to show the OLDGA account in the analytic accounts list. As you would suspect, it does not but rather simply gives access to the NEWGA version of that domain account.
So my dilemna is simple: at no point that I can find anywhere within the NEWGA analytics settings or listings a link to or reference to any of the OLDGA analytic accounts, even though my user in NEWGA has been given Admin rights to OLDGA.
You see my problem? I am trying to do exactly what you suggest, and what I know to be the process (in theory), yet there is no reference point in my accounts once I give Admin user access on how that user sees the other accounts/reports!
I have gone through all of Google's helps, blogs, and general web postings on the subject and the only aspect of the process listed is in the GIVING of the user rights. To my knowledge there is not one line of information anywhere that spells out in simple English:
"Now that you have access rights to another GA account, do the following to access those reports"
