Upgrading Critical Storage: Page 7 of 8

3. et up the new storage. Make certain to configure extra space on volumes that were running out of free space in the old system.

4. Replicate or copy to the new storage. Use a replication and synchronization system if you have more than a few gigabytes or the data changes regularly.

5. Ensure that backups are configured to handle your increased disk capacity. At a minimum, make sure you have enough tapes and that any added volumes are configured in the backup system.

6. Test the new storage after hours, possibly even failing over to it. The last thing you want to do is flip the switch without previous testing and end up with no storage.

7. Plan your final upgrade date with users in mind. Check with as many people as possible. Don't risk having a single business manager or system administrator say, "I didn't know, and it cost me money and productivity."
