Installation guide

For a migration, you must update your hardware to 64-bit, update the operating system to the 64-bit
Windows Server 2008 R2 operating system, update to SQL Server 2008 R2 or 2012, and update SQL Server
Reporting Services. Then you can migrate your existing VCM, SCM, or ECM installation to your new
VCM 5.7 environment.

VCM 5.7.
Prerequisites to Migrate VCM
Before you migrate any part of your existing VCM environment to VCM 5.7, you must perform several
prerequisite steps.
n Review and understand the migration scenarios. See "Upgrading or Migrating VCM" on page127.
n Verify that your existing VCM installation is functional.
n Verify that your VCM Collector meets all of the hardware and software requirements for a 64-bit
environment. For a complete list of requirements, see the "Software and Operating System
Requirements for Collector Machines" on page19.
n Verify that your VCM version to migrate is either VMware VCM 5.3, EMC Ionix SCM 5.0 or later, or
Configuresoft ECM 4.11.1 or later.
n If your VCM Collector is installed on a 32-bit Windows machine, understand the system requirements
for VCM 5.7. See "Software and Operating System Requirements for Collector Machines" on page19.
n Verify that an existing 32-bit environment includes SQL Server 2005 and SP3.
n Verify that an existing 64-bit environment includes 64-bit SQL Server 2005 and SP2, 32-bit SQL Server
Reporting Services (SSRS), and SSRS SP3. The 32-bit version of SSRS is required in 64-bit environments
of VCM 5.3 and earlier.
