Editing Landing Page Domain Name Prefix [CNAME]

Hey Community,

When we went live we used suga.sugarcrm.com....clearly that was not the best idea as we want to use info.sugarcrm.com going forward. I found articles that show how to add additional CNAMES, Add additional Landing Page CNAMEs (Administration)​, but what if we want to change all the existing LPs to the new format?  Is this possible?

Has anyone tried what I am talking about? Or is it just best to create the new CNAME, and build redirect rules for existing pages if needed to the new cloned Landing Pages?

Any feedback from users that have tried this and succeeded or failed would be great!
