Log into APPX as an APPX administrator. From the first menu select the System Administration pull-down, then File Maintenamce, then Database Files. Enter your database id in the first box and MPR in the second and press Enter. The screen should now show 23 of 23 Files Currently Selected. From this menu select Verify Files Menu, then Verify Integrity of APPXIO Files. If any of the files have a status of FAILED the data is corrupt. The data will need to be recovered before you go on with the upgrade.

After you have verified the data files log off of APPX and open an OS dialog window.

For these instructions we will use c:\appx as the directory where appx has been installed. For you site replace that with the actual directory path on your server.

Navigate to the c:\appx\data\ directory. Move down to the version directory for your site. Rename the MPR directory. A common practice is to rename it with todays date, like MPR_030311.

Unzip the MPR40_apps.tgz file into this directory. It will create a new MPR directory.

Move into the database directory and copy the MPR directory there to a new name in the same manner as above.

Unzip the MPR40_data.tgz into this directory. This should add the files LINKS.dat and LINKS.key into the MPR\Data directory.

Make sure permissions are properly set on these directories and files. On Windows the Everyone group should have Full Control. On Unix and Linux the owner should be appx and the group should be appxgrp or a group that has all appx users as members. Permissions should be set to 775.
