Re: Staging website is going live: Can we "globally" update the site domain URL across programs/assets?
So you mean that on your landing pages you have links to your main site that you want to mass update?
Or is your Marketo sub-domain also "staging-www" ?
I suspect that unless Marketo Support is willing or able to help, you won't be able to mass update links on the pages. They may be able to help if you are having the second issues. Give it a shot and ask 🙂
