Shouldn't install WebSphere 4.0.1 into WebSphere 3.5X directory without first uninstalling 3.5X

 Solution

 
Problem
Installing WebSphere Application Server (WAS) 4.0.1 into the same directory as an existing WAS 3.5 installing will not work correctly. Here is how to recover on a Unix system after installing WAS AE 4.0.1 into WAS 3.5X dir without first uninstalling WAS 3.5X.
 
Solution
This scenarios uses a WAS 3.5.3 Advanced Edition (AE) to 4.0.1 AE migration scenario.


Introduction

As a first step we would recommend archiving the WAS install directory before attempting this migration scenario, typically using the tar  command.  

On Solaris, removing of package repository entries is covered.

The following are steps provided by the WAS Install team for continuing migration when a 4.0.1 install was attempted (into the same directory as the 3.5 install) before uninstalling the 3.5 install, but after the first stage of migration or removing of the 3.5 JDK directory.  

A 4.0 install to the same directory as the 3.5 install should involve an uninstall of WAS 3.5 as well as removal of all non-migration directories from the install path before the second stage of the migration install is begun.

Steps

Steps to work around the migration problem resulting from migrating from 3.5.3 to 4.0.1:

Note:  Steps 2 and 3 are Solaris-specific.

1. Remove everything from the <was root> directory except the migration directory ( where you have backed up the 3.5.x
configuration and apps during the first stage of the install ).

2. cd /var/sadm/pkg. Remove all directories starting with WS* and itj*. ( These are WAS packages for 3.5.3 )

3. cd /var/sadm/spool. Remove all directories staring with WS* and itj*. ( These are WAS packages for 3.5.3 )

4. For an AIX installation:
  • cd /usr/lpp
  • Remove IBMWebAS* with the command rm -rf IBMWebAS* . Make sure that you are in the /usr/lpp directory before running this command.
  • Using AIX smit or smitty and remove every package which is the WebSphere package. All the WebSphere packages start with IBMWebAS.base.*

5. You should have the WAS_Migration_Temp.properties file in /tmp directory. If you don't, then you can copy it from the directory $WASROOT/migration/backup to the /tmp directory.

6. Now run the install.  It will automatically invoke the second step of migration.  It is not necessary to run the first stage of install, since all files are already backed up in the migration directory.

7. Choose either Typical or Custom for a successful completion of second step process of migration.
