5.1 Post-migration tasks

After the migration, you will need to perform several tasks. The list of tasks required depends on your actual environment. During the migration process, installation messages of the installp command are shown on the display console. The installp output goes to the file devinst.log, which is located in the /var/adm/ras directory. This file contains information on the software installed during the migration. We recommend that you view this logfile to see if all required software has been installed.

The BosMenus.log file located in the /var/adm/ras directory contains the migration menus and selections you have made during the migration. You can view and edit this file.

During the preparation phase, you should have compiled a list of tests and procedures that will need to be carried out to confirm the success of the migration and additional software. If at any stage during post-migration testing you discover a problem, you should be prepared to restore your system to its original condition, thereby allowing work to continue while you investigate, fix, or circumvent the issue. The point at which you must begin to restore the system depends upon the amount of time you have left before work must begin and the length of time it will take to restore the system. This point should have been determined while planning the migration and should be prominent on your migration schedules. As mentioned previously, before restoring the system to its original configuration, you may want to run the snap command and also take a full backup of the system. This will allow you to return to your existing state, when a solution to the problem has been found, without having to run through a full migration again.

Afew post-installation tasks are listed in the checklists in Table B-1 on page 44 and Table B-2 on page 45.

During our migration testing there was nothing needed to be done for CATIA and ENOVIA to operate. It continued to be run as it did on AIX Version 4.3.3 prior to the migration.

5.2 Migration experiences for AIX

The following sections provide information about our experiences with AIX made during the migration.

5.2.1 Umlaute on a German language keyboard

After the migration from AIX 4.3.3 to AIX 5L Version 5.1 the German umlaute did not work correctly. This is not a problem of the migration only. It also occurs if AIX 5L Version 5.1 is installed with the new and complete overwrite installation method. This problem might also occur with other languages.

To fix this problem, you need to install the X11.loc.de_DE fileset. You can either do it manually or provide a shell script executed by NIM after the migration process is finished. Example 5-1provides an example of the shell script we used during the migration:

Example 5-1 Example shell script

#!/bin/ksh

#

#This shellscript is executed after a NIM migration installation

#and installs the german locales for AIX 5.1 in order to support

#the German umlaute in a X11 environment.
