15.3 While uninstalling the eDirectory Server holding the CA, the KMOs created on that server will be moved to another server in the tree and become invalid
You should re-create the CA and KMOs for the tree. See
Creating an Organizational Certificate Authority Object and
Creating a Server Certificate Object in the NetIQ eDirectory 8.8 SP8 Administration Guide for more information.
We recommend that you do not uninstall the eDirectory server where the CA for the tree has been created.
