Installation guide

5. Perform de-referencing tasks (removing DAA references) on both the IMPAX 6.5.3 and the
temporary DAA clusters.
6. Attach an HSM server to the IMPAX 6.5.3 cluster and use Volume Migration Tool to migrate
archive data from DAA to HSM.
This is the upgrade method documented for IMPAX AS300 and IMPAX AS3000 6.2 or later clusters
using DAA.
Backup and restore migration with new hardware
(Topic number: 125325)
The following diagram depicts a backup and restore migration in which new hardware is deployed
instead of the existing servers being upgraded. This scenario is a non-parallel migration. If the site
is refreshing the entire production hardware, a traveling server may not be required. If using a
traveling server, the estimated downtime is the time to transition to the traveling server and back to
the migrated IMPAX 6.5.3 system.
IMPAX 6.5.3 with new hardware for Database
Server
IMPAX production system running earlier
version
After the new IMPAX 6.5.3 cluster is installed, the following high-level tasks are performed:
1. Restore a cold backup from the existing IMPAX production system to the new IMPAX 6.5.3
system.
2. Upgrade Oracle and the database schema on the IMPAX 6.5.3 system.
3. Perform de-referencing tasks on the IMPAX 6.5.3 system as required.
4. Upgrade any servers (such as Network Gateways) that are to be reused to IMPAX 6.5.3.
5. Transition to the new migrated IMPAX 6.5.3 system (on the new hardware).
This method is not the one documented in this guide, though the individual tasks are similar to
those done for the documented method.
