Upgrading a Single Server
This section describes the upgrade process from a single existing server to a single
5.2 server.
Installing the New Server
Proceed according to the instructions in Chapter 1, “Installing Sun ONE Directory
Server,” to install the new server on the same host as the existing server.
The new server must reside in a different ServerRoot location than the existing
server.ItmustalsobeidentifiedbyadifferentserverID.
NOTE If the existing 4.x server uses custom schema, ensure the migration
script can find the custom schema before migrating any data. Read
“(4.x to 5.2) Handling Custom Schema,” on page 55 for details.
Ifthemigrationscriptdoesnotrecognizethe customschema, it does
not migrate the schema, but instead applies standard schema files
after migrating the data to the new server. Applying the standard
schema to entries that conform to custom schema may render
modifications impossible, thereby making the upgraded directory
read-only.
NOTE Ensure you have a current backup of the existing server before
installing the new server.
