Is it possible to move an existing instance of Clarity from Windows to Linux?
You should be able to do this using these steps:
1. Do a clean install of the same version (and patch if applicable) of Clarity on the Linux environment (or Zip and copy the Clarity filesystem)
2. Point it to the current oracle database
NOTE: If you have any customizations to the file structure, then you would need to review those and make the changes in the new system accordingly.
