lab-time: upgrading grid infrastructure (gi) from 12.1 to 18c – the final version

In an earlier blogpost, I was playing around in an unsupported way to upgrade my lab Grid Infrastructure from 12.1 to 18c. The problem there was, that the 18c software was not officially available for on-premises installations. Now it is!

Exadata installation

Exadata installation

It was an exatastic day. One of our customers bought 2 exadata’s and zfssa’s. One for each datacenter. Sometimes a customer asks, how does it go. Together with a suggestion of Frits Hoogland (you can find him here: @fritshoogland) about creating an unboxing video, I came up with documenting the first steps in a simple blog.
