Can we change our CNAME

[Anonymous]

Hi, 

we have been using Marketo for a couple of years and created a lot of landing pages but now we would really like to change our CNAME to a much better one. Is it possible to do this and are there any risks we should keep in mind?

Thanks,
Mita

Hi Mita, it is possible to do this, and there shouldn't be any major issues with doing it. Here are a couple of threads discussing it, and there are others if you search for "change cname".

You essentially setup a new CNAME, then setup the domain alias for your OLD domain to point to the NEW domain.

Do this carefully to make sure the redirect works.
