To upgrade to eGuide 2.1.2, run the installation program, as detailed in Installing eGuide. During the installation, check the Backup Existing Settings check box. This accomplishes the following:
If the config_old, plugins_old, and templates_old directories already exist, the upgrade renames your current versions of the config, plugins, and templates directories to config_old2, plugins_old2, and templates_old2. If directoryname_old2 already exists, the files are renamed in sequential order all the way to the number 99. If you are unsure what your newest installation backup directories are, look at the directory time stamp.
NOTE: In eGuide 2.1.x, XML files are being used instead of ser files.
Make sure you select Backup Existing Settings. Otherwise, your existing properties directory is deleted and the installation continues.
