The following is tip #6 from "Managing Lotus Domino servers -- 15 tips in 15 minutes," excerpted from Chapter 14 of the book Lotus Notes and Domino 6 System Administrator Exam Cram 2, published by Sams Publishing.
A Lotus Domino server is decommissioned when it is no longer needed in the domain or when the users and databases are being consolidated to another server and the server is being permanently retired. Domino uses a tool called the Decommission Server Analysis tool to assist administrators in determining the impact on removing a server from the domain. When the tool is run, a database is generated that compares the existing server with the new server, so that the administrator has an idea what needs to be changed on the new server to guarantee a smooth transition. However, the database is meant to be a starting point and should not be considered an all-inclusive guide for all points that should be considered when using the tool.
For the Decommission Server Analysis tool to operate, both servers must be in the same domain and their hierarchical names must be consistent.
You must properly prepare for the server decommissioning process. Before decommissioning a Lotus Domino server, be certain you have taken care of the following items:
- Make sure that system backups are complete and verified.
- Verify that database formulas do not have explicit server reference information.
- Update configuration information in the directory that may have the existing server name defined in it, such as Connection and Program documents.
- Document all cross certificates and make sure that all certifier IDs are available to cross certify the new server.
- If the existing domain has Connection documents to external domains, be certain to notify the other domain administrators of the planned change.
- Notify users of the change.
- Verify that all protocols and named networks are set up correctly.
- Be certain that both servers contain matching databases with the same replica ID.
- Verify that all mail routing configuration information is correct and in place.
When you have verified that all of the preceding tasks have been performed, you can run the Decommission Server Analysis tool.
Complete the following steps to run the Decommission Server Analysis tool:
- Using the Administrator, select the Server tab and then choose the Analysis tab.
- Navigate to the Tools pane and Analyze tab. Select Decommission Server.
- A dialog box appears. Verify that the source server to be commissioned is correct.
- Select the target server that will replace the existing server.
- The default name for the Results database is DECOMSRV.NSF. If the name of the database needs to be changed, select the Results Database button and select a new database.
- The default setting for writing to the database is Append. Using this setting, if an existing database is in place, the tool will write the information to the end of the database. If Overwrite is selected, new results will be created and the previous information will be deleted.
- Select OK to use these settings and continue with the analysis.
When the tool has completed the analysis, the database should open to the Reports view. Examine the reports and correct any discrepancies before completing the decommissioning of the server.
