Migrate Beta2a to Beta3

Hi I'm in the progress of migrating our Beta2a install to a Beta3, as per the instructions

Migration Notes

After a couple of local access issues during -addTables, I oved onto step 5.

repotools-jts.bat -clean -migration_registerApplication fromApplicationPropertiesFile=rm-application.properties

However, for somereason I get the following output

Repo Tools
Provisioning using "D:\Program Files\IBM\JTS_BETA3\server\conf\jts\provision_profiles".
Jazz Foundation - Core Libraries, Version 3.0.1 Beta 3 (RJF-I20110325-0805)

The command "-migration_registerApplication" is not recognized.

So, has anyone else run in to this, have I missed something?

I have also raised a Work Item

Any advice or solutions would be welcome.
