FS4 devices with HP AC versions prior to 15.3.1
2.4 Supported devices / firmware revisions
Review the Release Notes for the new HP AC version for the list of supported devices. Firmware should
generally be kept up-to-date. Please contact HP for recommendations on any specific device or firmware
revision. Firmware updates can be completed any time before the HPAC upgrade.
2.5 Certificates
If using self-signed certificates, be aware that the default self-signed certificates type changed in HP AC
15.2. If upgrading from a version prior to 15.2, you will need to generate and apply new self-signed
certificates.
2.6 Time required
For in-place upgrades, when you run the HP AC Setup utility, the installer should recognize the existing
installation and run through that automatically with no user intervention required. Total time will vary, but
this typically takes less than 15 minutes per server to complete.
HP AC Job Accounting server upgrades may take longer because SQL database will typically need to be
updated.
2.7 Backup prior to upgrading
NOTE: Any file that has been customized or patched for the specific deployment should be backed up
unless HP has confirmed those patches are included in the solution update. Consult with HP on whether
these files should be put back into place following the update.
• We recommend performing a server backup or snapshot for virtual machines for disaster recovery
purposes prior to commencing the upgrade.
• For servers with Card ID Masking enabled, it is highly recommended to back up the
DataDecodeDefaults.xml files prior to upgrading. The AD-Authenticator DataDecodeDefaults.xml file is
located in the \HP Access Control\AD-Authenticator\ folder. The XT device DataDecodeDefaults.xml file is
located in the \HP Access Control\DPR\ folder.
• If using HP AC IPM, we recommend backing up rules. If needed, please contact HP for instructions on
backing up IPM rules.
• HP AC Authentication and Job Accounting databases should be backed up prior to the upgrade. HPAC will
upgrade database tables as required if the newer HPAC version requires it but the upgrade does not back
up databases.
• The C:\Program Files\HP\HP Access Control\bin\Config4.sdf file can be backed up to enable disaster
recovery of the HP AC Configuration Utility settings.
2.8 Determine order of the upgrade
1. Upgrade device firmware if necessary.
2. Upgrade HP AC client software on end user PCs.
3. For single-server environments, upgrade the HP AC server.
4. For multi-server environments, within each given data center:
a. Job Accounting / License management server first
b. Standalone HP AC Enterprise print servers next
c. Clustered or paired NLB servers must be upgraded
together
