Question : WASPreUpgrade Command issue

Hi,

I am trying to run the WASPreUpgrade.bat command on WAS V6.1 on windows environment.

the syntax I used is

D:\IBM\WebSphere\AppServer\bin>WASPreUpgrade.bat BackupV6 D:\IBM\WebSphere\AppServer -traceString "=all=enabled" -traceFile backuptrace.log

However for some reason I am getting this message
******************************************************************************************************************

IBM WebSphere Application Server, Release 6.1
Product Upgrade PreUpgrade tool, Version 1.0
Copyright IBM Corp., 1997-2005

MIGR0104E: You must specify the currently installed WebSphere Application Server directory name.
MIGR0001I: The class name of the WASPreUpgrade command is WASPreUpgrade
       
        >
        [-traceString [-traceFile ]]

MIGR0272E: The migration function cannot complete the command.

******************************************************************************************************************

As per the syntax I have given the WAS Current working directory as D:\IBM\WebSphere\AppServer

Well, I don't know for some reason I am getting the above error message..So can anyone please help me with this issue. whether I am making any syntax error while running the WASPreUpgrade command???

Moreover, do I need to stop the WAS server while running the WASPreUpgrade command or whats the best practice to run this command i.e the WAS server should be up or down?

or does this command stop the WAS Server automatically while it executes??

Please Advice !!!

Thanks in Advance

Answer : WASPreUpgrade Command issue

I presume that you are trying to migrate your 6.1 environment to 7.0.
So, the WASPreUpgrade command/script that you should execute is the one from the 7.0 installation, not the one from the 6.1 installation.

The 6.1 WASPreUpgrade script is looking for a version 6.0, or earlier that can be migrated to 6.1.
