Applying updates is a straight forwards process. You won’t lose your configuration if you follow the steps mentioned below.
- download the latest (newer) version of the IT search web application
- make a copy of the Windows directory where the web-application resides
- just in case something goes wrong
- stop the associated IIS application pool in the IIS management console
- select all files and folders in Windows Explorer where the web-application resides
- deselect the folder App_Data
- this is where your configuration database resides
- deselect the folder Resources (if it exists)
- this is where your logo resides, if you uploaded one
- deselect the folder App_Data
- delete the remaining files and folders
- unzip the downloaded version
- copy the files and folders from the zip to the web-application folder
- start the associated IIS application pool
- open the web application interface in your browser like http://search.domain.local
After that you should be all set. Of course, double check your configuration and make sure you can validate the search targets.
