6.2 Upgrade Process in 8.8 SP8
The ndsconfig upgrade command is used to upgrade the necessary configuration of the individual components such as HTTP, LDAP, SNMP, SAS, and NMAS. eDirectory database is upgraded to a new format if eDirectory versions prior to eDirectory 8.8 SP1 are upgraded to eDirectory 8.8 SP8.
The appropriate upgrade utility is called after the packages are upgraded to eDirectory 8.8 SP8.
A new offline database upgrade utility is available with eDirectory 8.8 SP1 onwards.
NOTE:In case the administrator wants to run the utility and find out the status of the upgrade, this database upgrade tool can be used with a copy of the database or with -d option

Using the Force Option to Upgrade eDirectory From Older Versions on Linux
eDirectory 8.8 SP8 only supports upgrades from version 8.8.2 or later on Linux.
To upgrade from eDirectory versions 8.7.3 through 8.8.1, perform any one of the following steps:
-
First, upgrade to eDirectory 8.8.7 and then upgrade to eDirectory 8.8.8.
or
-
Upgrade directly by using the force switch -f command.
With this option, some of the checks such as the health check and disk space check for DIB upgrade will not occur. Additionally, older RPMs are removed and new RPMs are installed.
