If you have any custom settings and/or dictionaries that you plan to reuse, you need to back up them before uninstalling, migrating, and upgrading.
- Back up the CustomDictionaries folder (<WebSpellChecker_Installation_Path>/AppServer/CustomDictionaries) with global custom dictionaries and its CustDictConfig.xml configuration file.
- Back up the UserDictionaries folder (<WebSpellChecker_Installation_Path>/AppServer/UserDictionaries) with all personal user dictionaries created by end users.
