Microsoft announced SQL Server 2019 CTP 2.3 in SQL bits (If you are not aware of what SQL bits is, it’s European version of SQL PASS) Keynote on Friday, first of March 2019. I really didn’t got chance to Install SQL 2019 initial release of CTP when it got released sometime around Sep 2018, In this blog post let’s take a quick Screenshot tour of Installing SQL Server 2019 CTP 2.3 on Windows Server 2016.
First thing first, we need to download media from Microsoft.
https://www.microsoft.com/en-us/sql-server/sql-server-2019#Install 
In this case, I am installing on Win Server 2016, So I picked Option 1.
As highlighted in the above screenshot, I opted to download ISO file and have a copy for myself so that I can use this to Install on a different machine in future without any hassles. Well, It’s all done in few mins…
Now, let’s go to the actual Installation part.
1.
2.
3.
4. I am interested in just the DB Engine for now.
5. Provided my service accounts
6. Time to configure Data Directories and don’t forget to visit TempDB tab.
7. Next—-> Next and Done!
Nothing fancy here with Installation. Now, I downloaded and Installed latest release preview of SSMS which supports SQL Server 2019 and below is the output of @@Version.
Note: If you have previous releases of 2019 CTP installed on the same machine, you can’t perform an Inplace upgrade to CTP 2.3, However you can have them side by side without any issues. In other words, It’s not required to uninstall previous release of CTP in order to Install 2019 CTP 2.3 as a different Instance.
BTW, my favorite feature of this release is “Accelerated DB Recovery and Instant Rollback for long running transactions”. There are few other new features added related to SSAS and Big data Clusters as well, but I am really not interested in those at this moment.
Cheers!
