2.) Copy over your users folder, prefs.xml, ssh private keys, and ssl keystores files from the old version to the new version's folder (see followup items below).\\
*Do not replace your WebInterface folder, the CrushFTP 8 WebInterface folder is very different, and replacing it with the older folder would break CrushFTP 8.\\

4.) Click Create New Admin User.  Create your own admin user that will be used for managing the server.  Call it 'crushadmin'.

6.) Login using the web browser to your server using the 'crushadmin' user you just created.  Click the 'Admin' button in the upper left.

7.) Go to Preferences, and click on each server item.  Verify to the right that each port (FTP,HTTP,SFTP) is set to use users from the correct User Connection Group.  (Probably "MainUsers" or "lookup_21".)

!!CrushFTP4 upgrade troubleshooting tips.


v4 has a bit of a mess on its user connection groups.  So when you look in the folder "users" you see MainUsers, lookup_21, lookup_80, etc.

Figure out which ones are correct.  MainUsers is the default location since v5.  But you can use the other named folders just fine too.

In the prefs, on the tab with the list of ports, down at the bottom is a list of the user connection groups.  Remove or add them as appropriate to match up with the real ones you have based on the folder names in the users folder.

Then on each port, check to see what user connection group they are configured for.  Assign them appropriately.

If you haven't done this then logins may fail when you start using CrushFTP8 as it can't find the users since they aren't associated to the port you are using.
