72 EMC Avamar 7.0 Release Notes
Installation
Upgrade requirements for Avamar with a Data Domain system
You must use DD OS 5.3.0 or later on a Data Domain system with an Avamar 7.0 server.
Before upgrading to Avamar release 7.0, clients backing up to a Data Domain system
must be running Avamar client release 6.1.x or higher.
Metadata capacity for backups stored on Data Domain systems
The
EMC Avamar Metadata Capacity Reporting and Monitoring Release 7.0 Technical Note
provides more information about metadata capacity for backups stored on Data Domain
systems. This technical note is available from EMC online support
(https://support.emc.com).
Microsoft Exchange 2003 and Data Domain
If you are backing up Microsoft Exchange 2003 to a Data Domain system, backups will no
longer work after upgrading to Avamar release 7.0. Support for Microsoft Exchange 2003
ended with release 6.0.x; there is no support for Microsoft Exchange 2003 in Avamar
release 6.1.x or later and upgrading to Avamar release 7.0 will permanently break
Microsoft Exchange 2003 backups to Data Domain. Therefore you must either:
◆ Upgrade to a later version of Microsoft exchange.
◆ Send the Microsoft Exchange 2003 backups to the Avamar system rather than Data
Domain using the Avamar release 6.0 Microsoft Exchange plug-in software.
◆ Continue to use the Avamar release 6.1.x server and do not upgrade your server to
Avamar release 7.0.
Required steps to upgrade from Avamar 6.1 to 7.0
Complete the following required steps in order when you upgrade from Avamar 6.1 to
Avamar 7.0:

1. Ensure that all Avamar clients are running Avamar 6.1 client software.
2. Upgrade the Data Domain systems to DD OS 5.3 or DD OS 5.4.
