Upgrading to Sierra...how?

[Trusteft]

Mac Mini late 2012
10.9

I downloaded Sierra but when it proceeds to install it doesn't let me to pick the HDD the Yosemite is on, with a pop up message that says what the attached screenshot shows
I am confused as to how to proceed.
If I go to system update window it only shows the button to install sierra (plus two software updates for fcx pro and one more). Nothing about updating to 10.10 or 10.11 or any other.

Hmm,
Take a good backup or two or three of your drive including server data.
Put the server app into the trash
Upgrade the OS
Download new server app

I know there is some good info in the blogs how to do a good backup and restore of server data. I can't find the links now.

I don't care about server app, not sure I ever even used it, or where to find it lol.
Thanks.

then trash the server app from your Applications folder, then install OS update.
