Uninstall/Delete Power Apps Portal completely from Dynamics 365

After installing 3 trial portals by using available templates  - Employee Self Service, Portal from blank and Community, I realized things are messed up. After browsing Community Portal unexpectedly it was showing "Employee Self Service" on home page, So I wanted to uninstall or delete Power Apps Portal completely from the environment and try by re-installing again.

 

Following things need to be considered about uninstalling/removing Power Apps Portal

• There is no uninstall option/button to remove the power apps portal
• Delete option for portal from  Power Apps maker portal
• Deleting the portal from the Power Apps maker portal only removes the portal web application and the portal app, it doesn't remove the portal metadata.
• You cannot provision a new portal if one exists or if it has been deleted; provisioning a new portal will use existing portal metadata.
• Resetting the portal from Administration site only reinstalls the portal web application.

 

To Uninstall/remove/delete Power Apps Portal completely

1. Delete the portal from the Power Apps maker Portal
2. Then delete the metadata from Common Data Service Environment using Power Management APP. Following entities store data for each portal which needs to be deleted. When you delete Website record associated with the Power Apps Portal related entity records gets deleted as well.
