Installation guide

(upgrades to IMPAX 6.5.3)
After the temporary DAA cluster is installed with IMPAX 6.2 or later software (the IMPAX version
currently being used in production), the following high-level tasks are performed:
1. Restore a cold backup from IMPAX 6.2 or later production system to the temporary DAA
cluster.
2. Detach the DAA server from the IMPAX 6.2 or later production system and make it part of
the temporary DAA cluster.
3. Upgrade the database, schema, and IMPAX software on the IMPAX 6.2 or later production
system.
(Upgrades of AS300 servers to IMPAX 6.5.3 are forklift upgrades, involving fresh installations
onto restaged or new hardware.)
4. Convert DAA entries to PACS Store and Remember on the upgraded IMPAX 6.5.3 production
cluster.
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.
For more details, refer to the AS300 Upgrade and DAA Consolidation Guide—IMPAX 6.2 or 6.3 to
IMPAX 6.5.3 or the AS3000 Upgrade and DAA Consolidation Guide—IMPAX 6.2 or 6.3 to IMPAX
6.5.3.
