Evan Martin created GEOS-4917:
---------------------------------
Summary: Windows installer should support upgrading from previous version
Key: GEOS-4917
URL: https://jira.codehaus.org/browse/GEOS-4917
Project: GeoServer
Issue Type: Improvement
Components: Windows Installer
Affects Versions: 2.1.2
Environment: Windows 7 x64
Reporter: Evan Martin
Assignee: Andrea Aime
Upgrading from one minor version of GeoServer to another on Windows currently involves these steps:
1) Make a copy of data_dir
2) Run the uninstaller
3) Run the new installer
4) Delete the newly created data_dir
5) Replace data_dir with the backed up version
This is error-prone and unintuitive. Most Windows programs happily perform an in-place upgrade simply by running the installer. I suggest that the GeoServer installer does the same, ie. delete old binaries (but not user data!) before installing the new version.
Currently, it APPEARS to do this, because it installs into the existing installation directory without any errors, but when the user actually tries to run GeoServer they get a confusing and completely unhelpful error (see GEOS-4914).
