When you upgrade to a new version of the server, the policies that were installed on the server by the earlier version are not overwritten. Instead, the current installation installs the policies with the new version names appended to their name.
This ensures that customizations already made in the existing policy are not lost. The administrator must compare the two policies and merge the changes in the new policy to the existing policy, keeping any needed customizations.
Specifically, in the case of migration from V6R2009x or upwards to V6R2013, the promote check trigger on all states of existing policy must be corrected from MCADPolicyPromoteCheck to PolicyMCADPolicyPromoteCheck.
