# ** NOTE:

# ** 1. You must uncomment and modify EVERY property

# ** 2. You can not perform migration and coexistence at

# ** the same time.

# ***********************************************************

# ***********************************************************

# The installer must be informed that you wish to operate on

# advanced AE

# AEs WAS Advanced Single Server Edition (V4.0.x)

# standard WAS Standard Edition (V3.x)

# Note:

# For migration from WAS V5.0.x, this field is not used. So simply

# set previousVersionPanelBean.selectedVersionEdition to “<NONE>”.
