Why does the confluence installer not present me with the option to upgrade?

[Scott Ortel]

I am upgrading my confluence server using atlassian-confluence-8.5.11-x64.bin.  However, the installer does not provide me with the option to upgrade just:

This will install Confluence 8.5.11 on your computer
OK [o, Enter], Cancel [c]

It is possible that this installation was moved from a previous location.  How does the installer determine if it is a new install vs. an upgrade?

Thanks,

Scott

Welcome to the community, @Scott Ortel 👋

First, let's confirm you are talking about the Data Center edition of Confluence and not the Server edition. (Your post is tagged with both tags.)

P.S. If you're unsure, navigate to https://my.atlassian.com/product to see license details, including whether your license is for a server or a data center.

I am migrating from Server to Data Center, so Data Center is the upgrade .bin. 

Update: I tried it again after restarting Confluence.  It seemed to prompt me for the upgrade option (as I'm used to).  Does Confluence need to be running in order for the installer to know it is an upgrade?  I'm still wondering how it knows, but I suppose it is not important now.

Thank you so much!

@Scott Ortel It knows it is an upgrade because of the previous install on the server.
