Audit verifies whether the source and destination machines comply with the requirements listed in /wiki/spaces/VDOC/pages/310706978. You can run the Audit check from the Administrative Console by clicking Run Audit before you find applications on the source machine, or from the CLI by executing https://virtamove.atlassian.net/wiki/spaces/VDOC/pages/314212459/virtaaudit?search_id=2f59b815-88d1-49ed-acca-e579a401ca5a.

For each pre-requisite, the Audit Report will indicate findings as follows:

Requirement

Description

Registry key value Com+Enabled

If the registry key value Com+Enabled in the HKLM\SOFTWARE\Microsoft\COM3 registry key is set to 0 (disabled) on the source machine, attempts to connect from the destination machine to the source machine and list COM+ applications on the source machine will result in an error.

If Com+Enabled is disabled on the destination machine, it will not be possible to list COM+ applications on the destination machine or install COM+ applications on the destination machine, which means that containers that have COM+ application packages will fail to dock.

Additionally, if RemoteAccessEnabled is disabled on the source machine, attempts to connect from the destination machine to the source machine and list COM+ applications on the source machine will result in an error.

Membership in the Distributed COM Users Group

The account used to perform the export (the account specified in the tether credentials) must be a member of the Distributed COM Users group on the source machine. Otherwise, the export will fail.

Configure your firewall to allow DCOM connections

You may need to configure your firewall to allow DCOM connections. For information, see:

https://campus.barracuda.com/product/archiveone/doc/46206124/how-to-configure-the-firewall-to-allow-dcom-connections/

complusnetwork registry key

For Windows Server 2003 Source Machines

To ensure that VirtaMove can access COM/COM+ components related to your application, the Application Server Role must be installed and the following key must be enabled (set to 1) on the source server:

Code Block
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\OC Manager\Subcomponents\complusnetwork

A reboot is not required after you change the value of this key.

For Windows Server 2008 and Higher Source Machines

For Windows Server 2008 and higher source machines, the complusnetwork key does not exist. However, port 135 must be open to allow VirtaMove access to COM/COM+ components. For more information, see: https://technet.microsoft.com/en-us/library/cc731967(v=ws.11).aspx.

...

For more information, see Antivirus.

Domain Controller

This section indicates whether the source machine is a domain controller, a server that responds to authentication requests and verifies users on a Windows domain.

...

A firewall comparison tool is available if you want to compare firewall rule differences or troubleshoot firewall issues between the source and destination. See Comparing Firewall Rules Group Policies between Source and Destination for more information.

Group Policies

...

The group policy section in the audit report indicates whether group policy information was successfully collected from the source and destination machines. If the audit was successful, then you can perform a group policy comparison using the https://virtamove.atlassian.net/wiki/spaces/VE/pages/309297809/Group+Policy Comparison tool+Comparison+Tool?search_id=8befec8f-bb8f-4f46-ac1d-6efb11f17c83 from the Administrative Console. If the audit was not successful, the audit report will indicate why group policy information could not be collected.

...

If Web Deploy 3.0 was installed on the source server and you subsequently installed Web Deploy 3.5 or higher in order to successfully migrate your application after the source and destination machines are connected via VirtaMove Source Agent, you will need to run

...

on the destination server so that the destination server will recognize the new installation of Web Deploy on the source server. It indicates whether Web Deployment Agent is installed and started.

...

VirtaMove Source Agent communicates through TCP port number 9665 by default. You can configure the port number to a different number if required. See https://virtamove.atlassian.net/wiki/spaces/VDOC/pages/311263870/VirtaMove+Source+Agent?search_id=ad789219-0efd-43c1-83fa-db74b84f128b for more information.

If the Audit Report indicates that a required port is closed, makes sure that external nodes between the destination machine and the source machine also permit communication across these ports (port 445, 9665, etc.). For example, if you are migrating across a cloud managed by to an Amazon Web Services (AWS) managed cloud server, make sure that AWS also has these ports opened.

...

Remote Access must be enabled to accept COM requests , and may be required for DCOM.

To enable remote access, the registry key values Com+Enabled and RemoteAccessEnabled must be set to 1 in the HKLM\SOFTWARE\Microsoft\COM3 registry key on the source machine. The Remote Access enabled value is used in the COMPlus check. Enable the key as follows:

...
