Jess Pomfret uses this T-SQL Tuesday to cover some of her favorite cmdlets in dbatools:
Test-DbaSqlBuild
When I found this command I couldn’t have been more excited. My day-to-day job requires the care and watering of over 100 SQL Server instances of varying versions. Using this command you can get the current build of all your instances and then compare that to the most recent available. There are also parameters for how far you want to be from the latest version. Setting the -latest switch means just that, your server will only be seen as compliant if it’s on the latest release, passing in -1CU means that it can be no more than 1 cumulative update behind.
Read on for a few additional useful cmdlets. Out of a large number of useful cmdlets.
