Dear Marketo team,
Currently we are building one of our campaign in Sandbox as pilot and would like to migrate the same into Production in near future. Could you kindly help us with the steps how we can achieve that.
We will really appreciate if you can points to to any help pages / document in regards to the same
This is pretty easy. Find the account string from your Production and Sandbox (under Admin > LP).
Then send a ticket to Support to ask them to connect your accounts so you can use Import Programs. Provide the accountstring along with the email address of one of the Marketo Admins that exists on both instances.
That should do it. Once it is done, you can go to Production > Import Program > and choose an instance.
