Changing the Index Server for the Exchange Mailbox Agent

If you need to replace the client that performs the role as the index server, you must perform the procedure in a specific order to transfer the current index to the new client.

Note

When you change the index server or the index directory, it is recommended that you backup the index server rather than reconstruct. For more information, see Backing Up the Exchange Mailbox Agent Index Server.
Full index reconstruction is recommended only when index server backup is not possible or is not available.
For any configuration changes to the index server, see Index Server Configurations.

Procedure

Create the new index server.
From the CommCell Browser, expand Client Computers > Exchange Mailbox client.
Right-click the agent, and then click Properties.

The Exchange Mailbox Properties dialog box appears.
On the General tab, select the new index server from the Index Server list.
Click OK.

A message appears that tells you that the index will be reconstructed.
Click Yes.
To see when the reconstruction job is complete, on the index server, open the IndexServer.log that is located in the software_installation/ContentStore/Log Files folder.

When the reconstruction is complete, you will see the following strings in the log file:
```
IdxExchangeApp::SubmitCommitChunk() - CommitChunk
 ...
 IdxLuceneApp::CommitJob() - Finished playing all log files, doing job end processing
 ...
 IdxLuceneApp::CommitJob() - Job end processing done
```
If the reconstruction was successful, you should see messages that were archived before and after you changed the index server.
