Support policies for AppZero products

AppZero Software product support is provided to customers and partners using AppZero products under the following constraints:

The application to be migrated must reside on a supported Source server running the Windows Operating System. The following versions of Windows are currently supported as Source server environments:

  • Windows Server 2003 (32-bit and 64-bit)
  • Windows Server 2003 R2 (32-bit and 64-bit)
  • Windows Server 2008 (32-bit and 64-bit)
  • Windows Server 2008 R2
  • Windows Server 2012
  • Windows Server 2012 R2

AppZero Software must be run on a supported Destination server running the Windows Operating System. The following versions of Windows are currently supported:

  • Windows Server 2008 R2
  • Windows Server 2012
  • Windows Server 2012 R2
  • Windows Server 2016

The customer must be running a supported version of the AppZero product. Our product lifecycle policy specifies that a particular version of AppZero, including any service packs to that version, remains supported for 6 months after the next version is released.

Customers requesting support on a version of AppZero that is no longer supported may be asked to upgrade to a supported version to facilitate resolution of the incident.

Clean destination machine

For best possible results, AppZero requires a clean destination machine, which is a server on which no applications other than AppZero are installed and on which updates and patches have been applied to the operating system.

Support policy for migration of third-party applications

AppZero is an application migration technology which extracts previously deployed applications from Windows Servers and packages them for migration and deployment to more modern infrastructure including new servers, new operating system versions, and/or cloud operating environments.

AppZero is a general purpose migration technology that can be used to migrate a broad range of business applications residing on Windows Server, including multi-tier applications, database servers, custom applications and 3rd party packaged applications.

There is no explicit supported applications list for use with AppZero. Rather, AppZero will make reasonable efforts to provide support, including both usage recommendations and defect resolution, to customers attempting to migrate any application that isn’t known to be incompatible, or until a specific incompatibility is found. The following applications are currently known to be incompatible:

  • Microsoft Exchange
  • Microsoft SharePoint
  • Microsoft Active Directory services
  • Any application embedding Internet Explorer
  • Any application which includes kernel drivers
  • Any 16-bit application

AppZero migration and 3rd party vendor support policies

AppZero migrates the application artifacts from an existing installation of an application to a new server, by moving files and registry entries from an old server to a new one, with the end result similar to that of a backup and restore cycle. The process is very reliable and the end result is usually indistinguishable from a natively installed application.

Most application vendor support policies neither endorse nor preclude the use of IT operations tools like AppZero. However, the support staff of a vendor-supported application will likely not be familiar with the AppZero migration process and may be reluctant to diagnose application issues during the course of a migration, if the issue is expressed in terms of the AppZero migration workflow.

AppZero can also be used to move an application from a particular version of Windows where it was installed, to a later version of Windows. As such it may enable the application to be moved to a version of Windows for which it is compatible, but that is not a supported Windows version for the application.

When moving an application to an “up-level” version of Windows, customers should exercise discretion in assessing what version of Windows the application vendor supports for the current version of the application, whether application upgrades are necessary to ensure the application is supported on the target version of Windows, and if so applying those upgrades after the migration.
