SQL SERVER – Installation Failure – Specified Instance Via Transform is Already Installed. MSINEWINSTANCE Requires a New Instance that is not Installed
This is one of the situations where my client installed one clustered instance of SQL Server and the second one was failing. In this blog, I would share my findings of error: Specified instance via transform is already installed. MSINEWINSTANCE requires a new instance that is not installed.
A couple of months ago I told you about the new interesting tool I found for documenting existing database schemas – Dataedo. For those who don’t remember, this is a desktop tool that enables you to describe database schema elements and create ER diagrams for existing databases, and export to nicely formatted HTML and PDF documents.
A complete and precise documentation serves a good basis for developers and DBAs during their onboarding to get a general picture of the database they start working with. Creating such a documentation manually takes a lot of time and effort. So you seat for hours and hours digging through the database structure figuring out its functionality, data types stored therein, building relationship diagrams, etc. Moreover, every time changes are introduced to the database, you have to get back to it update the documentation by hand. This definitely feels like a burden and you keep delaying it until the last minute.
