Availability values: https://learn.microsoft.com/en-us/dotnet/api/microsoft.sqlserver.management.smo.compatibilitylevel

-InputObject

A collection of databases (such as returned by Get-DbaDatabase)

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

-WhatIf

Shows what would happen if the command were to run

-Confirm

Prompts for confirmation of every step. For example:
Are you sure you want to perform this action?
Performing the operation "Update database" on target "pubs on SQL2016\VNEXT".
