Moving A CNAME From An Old Instance To A New Instance

Description description

A CNAME needs to be moved from an old instance to a new instance

Resolution resolution

NOTE: You cannot have the same CNAME in two different instances (Pointing to two instances, e.g. cname1.company.com pointing to instance1.mktoweb.com and instance2.mktoweb.com)

Key terms:
CNAME 1 = Initial cname in the old instance
CNAME 2 = Additional cname created in the old instance
INSTANCE1 = Old instance (Instance Name)
INSTANCE2 = New instance (Instance Name)

Phase 1

  1. Create an additional CNAME (a replacement CNAME) which you would want to swap as the default in the second step.
    CNAME 1 > INSTANCE1

    (Default) < Existing CNAME in the Marketo Admin > Landing Pages section>

    CNAME 2 > INSTANCE1

    This would be the additional CNAME created for the replacement.

  2. Swap the default with the replacement CNAME you just created in step 1 and set this CNAME1 as a domain alias in the old instance.
    CNAME 1 > INSTANCE1

    A domain alias in the old instance.

    CNAME 2 > INSTANCE1

    (Default)

Phase 2

** Transition might not be smooth during the cutover. :) (The Landing page links might get some interruption during the cutover)

During the Cutover (Before the old instance deactivated) :

  1. [ Your Action] - To remove the CNAME1 which is a domain alias in the old instance (INSTANCE1)
  2. [ Your Action (IT Team)] - To create CNAME1 as a domain alias in the new instance (INSTANCE2).  (During this time the link to old landing pages will be broken)
  3. [ You need to raise a support ticket to enable SSL for CNAME1 for the new instance (INSTANCE2).
