If you fail to perform the upgrade steps or you perform the steps out of sequence, then
backup failures and data corruption on the backup device can occur.

2. Ensure that all Avamar clients are running Avamar 6.1 client software.
3. Upgrade the Avamar server to release 6.1.
4. Upgrade the Data Domain systems to DD OS 5.3 or 5.4.
5. Upgrade the Avamar server to release 7.0.

Upgrade requirements for Avamar Extended Retention
If you are upgrading from Avamar release 6.1.x to Avamar release 7.0, the Avamar
Extended Retention software must be upgraded to 2.1.
Upgrade requirements for Avamar with NetWorker
If you use Avamar with EMC NetWorker
®
, review the minimum NetWorker software version
requirements before you upgrade the Avamar server to release 7.0. The
NetWorker
Software Compatibility Guide
on EMC Online Support at https://support.EMC.com
provides information on the NetWorker version requirement for specific clients.
Upgrade requirements for environments with LDAP
If you upgrade to Avamar 7.0 from Avamar 6.0.x or earlier and you use LDAP to perform
external authentication for either Avamar Administrator or Avamar Desktop/Laptop, then
you must configure a new LDAP environment.
The way that Avamar communicates with the domain controller and the external
authentication server by using LDAP is different in version 6.1.x and later.
If there is an active older LDAP configuration, then the upgrade process disables the new
LDAP configuration method and maintains the older LDAP components without
transferring the old configuration values to the new method.
The
EMC Avamar Administration Guide provides details on configuring the new LDAP
environment.
