Preinstall or preupgrade procedure

Back up system resources and databases, as described in Backing up system resources and data.

Determine whether you will be using per-Exchange-server SnapManager licensing or per-storage-system SnapManager licensing.

For more information, see Understanding SnapManager license options.

Ensure that the SnapManager COM server identity account on each Exchange server to be used by SnapManager has Exchange Administrator permissions or greater, as described in Understanding SnapManager COM server identity account requirements.

If you need to change an object's permissions, do the following from within the Exchange System Manager:

1. Right-click the object and select Delegate Control.
2. In the Exchange Administration Delegation Wizard, change that object's permissions.

Configure or upgrade your storage system according to the requirements for SnapManager and SnapDrive, described in Understanding storage system requirements.

You might need to install or upgrade any of the following components:

• Data ONTAP
• iSCSI and/or FCP protocols
• SnapManager license
• SnapRestore license
• SnapMirror license

Upgrading from a previous version of SnapManager. If you will be upgrading SnapManager and you also upgrade underlying SnapDrive or Microsoft iSCSI initiator versions, make a note of this now. Later, while preparing to upgrade the SnapManager application (described in Before you begin the upgrade procedure), you must remove the iSCSI dependency with respect to SnapManager.

Note whether your storage system has multiple IP addresses.

Configure or upgrade your Windows host systems to meet the requirements for SnapDrive and SnapManager, described in Understanding Windows host system requirements.

You might need to install, upgrade, or configure the following components:

• Microsoft Windows operating system
• Microsoft Windows hotfixes
• Microsoft Exchange
• SnapDrive
• SnapDrive preferred IP address (if your storage system has multiple IP addresses)

  For details, see the SnapDrive Installation and Administration Guide for your version of SnapDrive.

  Note
  If you do not configure a SnapDrive preferred IP address for a storage system that has multiple IP addresses, SnapDrive times out when attempting to create Snapshot copies simultaneously for more than one LUN on a storage system.

• Data ONTAP VSS Hardware Provider
• iSCSI and/or FCP protocols

After you complete these tasks, you are ready to install or upgrade SnapManager. Proceed to Installing or Upgrading SnapManager.
