You can now upgrade your Free tier database to the Professional tier without downloading a dump file and then loading it. It works similar to the Clone database feature by making a copy of your database into a new Aura Professional instance.  

 

To upgrade, simply do the following:

1. Click on the ellipsis (three dots).
2. Select Upgrade to Professional.
3. Walk through the Database Creation Wizard.
4. Download the instance information/preserve the password.

Note that

• The new Pro Tier database will have a new DBID; i.e., and the connection URI will change when you move from Free to Professional.
• This operation is not destructive of the free tier database.
