When you uninstall eDirectory and install it again, the eDirectory server cannot be accessible to the other servers in the network. All the distributed operations such as synchronization and obituary processing do not take place on the partitions whose replicas are present in the eDirectory server. If this state persists for a while, it might impact all the servers and the processes running on them.
Avoid uninstalling a newer version of eDirectory and install an earlier version, because:
Does not revert the schema related upgrades.
eDirectory might not be functional if DIB is upgraded to the newer version.
Removes all the existing configuration files, except for the nds.conf.
However, consider the following when you uninstall a newer version of eDirectory and install an earlier version:
Upgrade the DIB to the newer version. Else, eDirectory might not be functional.
Back up the existing configuration files, except for the nds.conf, and restore when eDirectory is installed again.
Does not revert the schema related upgrades.
