Installation & Upgrade / Migration aspects Installation requirements Installation methods on different supported platforms Local installation via script Limitations / drawbacks Migration aspects Upgrade considerations Upgrade scenarios -OBII 4.x - DP 5.0 -OBII 4.x CM on HP-UX 10.20 - DP 5.0 CM(on HP-UX 11.x)

Installation requirements (1) Unix platform: HP-UX, Solaris 7 and 8 RAM (MB) Disk Space (MB) Cell Manager ** 256, recommended 512* 220 Installation Server 64 240 (350 for Solaris) User Interface ** 64 120 Disk Agent 64, recommended 128 10 Media Agent 64, recommended 128 10 Integration Modules 64, recommended 128 10 * The required memory (RAM) depends on the number of parallel sessions ** DP 5.0 Cell Manager and GUI are NOT supported on HP-UX 10.20 anymore!

Installation requirements (2) Windows platform: NT4.0, W2000 and XP RAM (MB) Disk Space (MB) Cell Manager 256, recommended 512* 190 Installation Server** 64 160 User Interface 64 100 Disk Agent 64, recommended 128 10 Media Agent 64, recommended 128 20 Integration Modules 64, recommended 128 15 * The required memory (RAM) depends on the number of parallel sessions ** DP 5.0 Installation server is NOT available on Windows XP

Installation methods (1) Target platform Installation tools HP-UX Installation Server Unix Windows swinstall, swremove Solaris pkgadd, pkgrm Other Unix omnisetup 1 Windows Microsoft Installer Novell Install script MPE/iX ftp, unpack 1) Installation server does not support Dynix, SCO Unixware 7.1.1 client

Installation methods (2) New install script for local installation of Unix clients: omnisetup.sh Applies only for non HP-UX 11.x and non Solaris Unix clients omnisetup.sh [-source directory] [-server name] [-install component-list] -directory is the location where installation CD is mounted. If not specified, current directory is taken. -name is an optional name of the cell server host. -component-list is a comma-separated list of component codes. No spaces are allowed, and core and core-integ components need not to be specified. Located on CD for HP-UX, in directory LOCAL-DP-AGENTINSTALL Only ksh shell is supported Detects and upgrades previously installed components Checks and validates specified components Client host can be imported automatically

Limitations / drawbacks DP 5.0 CM and GUI not supported on HP-UX 10.20 No DP 5.0 CD for HP-UX 10.20 Installation server not supported on Windows XP ’Automatic disaster recovery’ module only installable on Windows platform No Japanese, German and French localization

Migration aspects No license migration required ! Only support contract migration IDB structure unchanged, but new Velocis DB version Direct upgrade is possible for: -OB II A.03.51 - Data Protector A.05.00 -OB II A.04.00 - Data Protector A.05.00 -OB II A.04.10 - Data Protector A.05.00 Upgrade from other Omniback II versions: -first upgrade to OB II 4.x required -OBII 3.x - OBII 4.x - DP 5.0 (possible, but not recommended) -direct upgrade from OBII 3.x - DP 5.10 planed with DP 5.10

Upgrade considerations Requirements to consider: CM, IS and clients must have same version installed (DP 5.0) In MoM environment all CM must have same version installed (DP 5.0) Licenses of OB II A.03.x and 4.x still valid in DP 5.0 no license migration needed Important: upgrade procedures are different on HP-UX, Solaris and Windows platform - on HP-UX and Solaris: first remove old, then install new binaries IDB and configuration data will not be removed - on Windows do NOT remove/uninstall old binaries ! otherwise IDB and configuration data will be removed Upgrade order: 1. Upgrade cell manager and all installation servers 2. Upgrade all clients, can be done gradually 3. MA / Integration Agents must be upgraded before start of any backup / restore

Upgrade scenarios (1) Upgrade from OBII A.04.x DP A.05.00 Standard upgrade procedure applies Upgrade consist of conversion to new Velocis DB version (2.0 - 3.5) IDB data files will not be modified IDB upgrade started automatically after installation, no user interaction required SW install and remove utility is swremove / swinstall on HPUX and MSI on Windows IDB upgrade very fast Upgrade status reported in upgrade.log file

Upgrade scenarios (2) Upgrade OBII 4.x CM on HP-UX 10.20 DP 5.0 on HPUX 11.x DP 5.0 does NOT support CM and GUI on HP-UX 10.20 Upgrade procedure needs to incorporate upgrade of HP-UX to 11.x Order of upgrade steps very important: 1. Remove OBII 4.x binaries from HP-UX 10.20 CM (swremove) 2. Keep IDB and configuration data untouched 3. Upgrade system OS to HP-UX 11.x 4. Install DP 5.0 binaries (using swinstall) 5. Installation process automatically upgrades IDB

IDB Upgrade Wizard - detail part (1) This upgrade wizard offers three options to proceed: Upgrade detail part of IDB Postpone the detail upgrade Skip the upgrade and finish installation

IDB Upgrade Wizard - detail part (2) This upgrade wizard checks: OBII 3.51 database Disk space required for detailed upgrade

IDB Upgrade Wizard - detail part (3) This upgrade wizard allows: Add extension files for filename table spaces Add directories for binary files (DCBF directories)

IDB Upgrade Wizard - detail part (4) This upgrade wizard provides: Estimated time required to perform the detail upgrade Allows to monitor the progress of the detail upgrade
