Change DNS GTM Self IP

Greetings,

My approach is to take the DNS I will not change out of the sync group. Then, change the LTM gateway pool, and Link, listener, self address on the DNS, then change LTM VS addresses. After that join the other DNS to the sync group running gtm_add <dns_on_syn_group>.

Let me know if there is a KB for this change, I didn't find it or if any of you have done that.
