Can I use GAM with multiple domains?

I need to run some GAM scripts across two domains as a client is migrating; is this possible? I've been trying to find any documentation on setup but there doesn't seem to be :/

Any help is appreciated!

Note: This is not a question about primary or secondary domains - if you need more information on primary/secondary switching I've found GAM3DirectoryCommands to be very helpful and descriptive!

Solution

It's not directly possible; however you can achieve this in the following manner:

create a CONFIGS folder (you can actually call this wahtever makes sense to you), and a sub-folder for each domain
move your client_secrets.json, oauth2.txt and oauth2service.json files from you GAM install folder into your newly-created domain folder
run gam info domain and gam info user to see how this affected your gam install
to create a new domain setup, run gam create project
once complete, run gam info domain and gam info user again to see the difference
remember to save your new config to your CONFIGS folder for this new domain too!
when you've replaced the config files, run gam user <your_admin_account_for_the_current_domain> check serviceaccount before running any commands, otherwise you're likely to get some errors ;)

Now you can switch between domains by replacing client_secrets.json, oauth2.txt and oauth2service.json in your GAM install folder (and remember to check serviceaccount).

Obviously there are many more elegant ways to do this - but this will form the basis of your powershell script in any case ;P

Hope this helps!
