Preserving the System User List and Device Information

Before you begin you may wish to create a backup copy of your current DP4 installation, so that you can revert to it if necessary.

From release 4.621 the install program will automatically preserve information from the system database when upgrading a previous DP4 installation. It does this by automatically following the second variant of the procedure descibed below. Up to release 4.620 you need to follow this procedure manually.

To preserve information from the system database proceed as follows:

1. Export the User list from the existing system database. This is the list of users and their passwords as set up using MENUUSER.

   Run MENUEDIT -DB SYSTEM
   • Select Users table
   • Select Print user list

   • Print the user list to a file, so that you can re-load the information when the new system is loaded

   From release 4.621 the command menuedit -users -print -file filename will export the user list to filename without user intervention and then exit menuedit.

2. You must export the Device setup from the existing system database. This is the set of printers and devices (and logical devices) set up using DFSETUP. Run DFSETUP
   • Select Printer characteristics
   • Select Export device information

   • Print the device information to a file

   From release 4.621 the command dfsetup -export -file filename will export the device list without user intervention and then exit dfsetup.

3. Run the install program (see Installing Additional Products ) and:

   • Install the "Windows Programs" in the same directory as before, for example, C:\DP4\WIN

   • Install the "System database" product in the existing database directory, for example, C:\DP4\DB

4. Re-load the user list

   Specify the filename you used for step 1 above in place of users.prn:

   MAPPOST -DB SYSTEM -quiet users.prn

5. Re-load the device information. Specify the filename you used for step 2 above in place of devices.prn:

   MAPPOST -DB SYSTEM -quiet devices.prn

   If you like you can combine the previous two steps by specifying both filenames on the same command line:
   MAPPOST -DB SYSTEM -quiet users.prn devices.prn

If you are upgrading from quite an old version of DP4 it may be the case that some of the standard print devices have changed and should not be preserved. In this case you need to follow a slightly different procedure after step 4

5. Repeat step 2 above to export devices from the new system database. Use a different filename from before.

6. run MAPPOST -DB SYSTEM -overwrite -quiet devold.prn devnew.prn
   where devnew.prn is the filename you used to save the print devices from the new system database, and devold.prn is the name you used to save devices from the original system database.

This will ensure that any "standard" devices will be defined as issued by Itim.
