Top level domain change process/steps?

[Viki_Sparks]

Hi All, 

We are planning change the top leave domain form info.123.ab to info.123ab.com. We have also, previously migrated from info.123.com to info.123.ab. We still have Landing pages working with assets bearing the info.123.com.

If that was confusing, below is the table, 

Domain	info.123.com	info.123.ab	info.123ab.com
Age	Old Domain	Current Domain	New Domain
Status	Active on Assest URLs, Redirected to current domain	Active - Primary	Yet to migrate

We want the redirects to happen from (Old Domain to New Domain) & (Current Domain to New Domain) as well.

Can someone tell me the steps that are involved in this migration and we don't want to loose the cookies.

Thanks in advance

.ab is not a valid TLD.

You must supply your real domains; forging fake domains is not useful if you want to get help.
