I want to make sure all trial BaaS users see the comment on the BaaS Sunset post: https://community.apigee.com/comments/58082/view.html
Even though BaaS customer orgs are planned to be available until mid-2019, trial BaaS orgs are scheduled to be disabled in mid-July 2018. Please plan accordingly.
Just to add to your info,
No traffic will be accepted by Apigee BaaS Evaluation orgs on or after July 23, 2018.
