+#### Upgrading to 14.16
+
+Chef Infra Server 14.16 includes a fix for the growing bifrost database. Due to this bug there would be unused authorization ids created in the bifrost database. After upgrading to 14.16 , the unused authorization ids needs to be deleted.
+
+Use the following command to analyze the data that gets deleted. This also gives the rough estimate of the time need to delete the data.

+```bash
+chef-server-ctl cleanup-bifrost --estimate-only

+Use the following command to delete the unused authorization ids from the bifrost database

 ##### Database Preparation
 
 1. Run `VACUUM FULL` on the PostgreSQL database if you don't have automatic vacuuming set up. This process will reduce the size of the database by deleting unnecessary data and speeds up the migration. The `VACUUM FULL` operation takes around 1 to 2 minutes per gigabyte of data depending on the complexity of the data, and requires free disk space at least as large as the size of your database.
