Note: Qvera makes every effort to maintain backwards compatibility, however, it is possible that an upgrade could change the database backend such that rolling back to a previous version would not be possible.
1. Locate the QIE home directory (usually in C:\ProgramData\QIE). To locate the home directory, navigate to the QIE Service Manager tool and click on the Java tab. The QIE home directory will be listed under the Java Options section.
2. Locate within the QIE home directory the "qie.war" file. Note you may need to uncheck the "Hide extensions for known file types" option in the windows folder options to see the war file extension.
3. Stop QIE
4. Rename the qie.war file or copy the file into another directory.
5. Locate the most resent "preUpgrade_{date}" folder within the QIE home directory and copy the qie.war file from within this directory back into the QIE home directory.
6. Re-start QIE. QIE will now start back up with the previous version running prior to the upgrade.
To move back to the upgraded version
a. Stop qie
b. Put back into the QIE home directory the file that was renamed or moved in step 4
c. Restart qie
