How to upgrade a Heroku PostgreSQL database to a new plan

I started a project on a Hobby Dev plan (free, limit 10,000 rows), and then later needed to upgrade it to Hobby Basic ($9/month, limit 10,000,000 rows).

After assigning the new database, I had two databases attached to the application. They looked something like this:

HEROKU_POSTGRESQL_OLIVE (postgresql-dimensional-3321) Old, free-tier (Hobby Dev) database

On hypervisor (probably your workstation)

yum install virt-who
Edit /etc/virt-who.d/test.conf and update the rhsm_hostname, rhsm_username, rhsm_password (use dev server credentials)
