How to upgrade FTP Synchronizer from v2.3 to latest version?

I) If you don't want to use current configurations:
Simply install the new version and overwrite current installation.

II)If you want to use current configurations:

• 1) Please run all profiles in current version to make sure all files were synchronized successfully.
• 2) Download a small utility from our web site
  http://www.ftpsynchronizer.com/ftpsprofileconvert.exe
  This utility helps you to convert all configurations to new format.
• 3) Close the FTP Synchronizer if it's running. Then, launch the ftpsprofileconvert.exe
  to convert all configurations. (This utility will not delete the old configurations)
• 4) Download and install the new version
• 5) Run the new version of FTP Synchronizer. You should see all profiles in it.
• 6) When you preview a profile, you may see FTP Synchronizer wants to update unchanged files again. Please press 'Ctrl+A' to select all items, right click the mouse and select 'Mark as Unchanged'. Then, please run the profile. This step is very fast and it will *not* transfer these files.
