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
-
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
>INSTANCE1This would be the additional CNAME created for the replacement.
-
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>INSTANCE1A 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) :
[Your Action]- To remove the CNAME1 which is a domain alias in the old instance (INSTANCE1)[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)[You need to raise a support ticket to enable SSL for CNAME1 for the new instance (INSTANCE2).
