Is it possible to port cookies?

[Anonymous]

We've been using Marketo for about a year but are planning on changing our primary domain used.  Is it possible to port all the Marketo cookies that have accumulated over the past year?

Hi Matt.
Cookies are stored locally on browsers so you do not have access to your clients' cookies. 

For a lead to be cookied on your new domain, they will either have to fill out a form on that domain or click on an email link that directs them to that domain. It is also possible to give a lead a cookie with an associateLead API call. This is especially useful if users login to your website.

Best,
Will

Will,
Sorry - potential rookie question here but... Since the cookies are encrypted via Marketo, can't Marketo read across domains?

Thanks

My understanding of cookies is that, for security reasons, they will only work for one domain. There is some custom scripting you can do (http://stackoverflow.com/questions/315132/how-do-i-use-cookies-across-two-different-domains) but it is generally not advised as this is an exploitable security risk.
