This bug is referenced in ovirt-engine-3.4.0-beta3 logs. Moving to ON_QA
Creating 3.0 DC and editing to 3.4 doesn't give informative popup (like asked in the description) .
I got -
You are about to change the Data Center Compatibility Version. Are you sure you want to continue?
TCMS run - https://tcms.engineering.redhat.com/run/119792/
My mistake, configuration issue,
You are about to change the Data Center Compatibility Version. This will upgrade all the Storage Domains belonging to the Data Center, and make them unusable with versions older than 3.1. Are you sure you want to continue?
I know this is stating the obvious, but this is going to make it into future revisions, right? Not just 3.1 as this bugzilla states?
DC 3.0 uses SD v1 and v2,
Starting 3.1 we are using only SD v3
which means that in case you upgrade the DC version we will change the SD version.
It doesn't matter to what version, 3.1 or above.
