Overview 

When a server is migrated from a physical server to a virtual server, ShadowProtect may need to be activated again. If this occurs, normally when ShadowProtect is reactivated it will force a new full backup. Follow the steps in this article to avoid this from occurring.

Instructions 

When you deactivate a ShadowProtect license and put in a new one the ShadowProtect software will see a new registry key and will think it needs to take a new base image. You can use the commands below before you deactivate the ShadowProtect key to pull the appropriate registry entries, so that you can reimport them after migrating the server. After the server has been migrated, enter in the new ShadowProtect license key and then run the reg commands below to have it continue on the current incrementals.

Before you migrate: 

reg export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ShadowProtectSvc\Parameters\Jobs c:\SPBackupJobs.reg
reg export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ShadowProtectSvc\EmailOptions c:\SPBackupEmail.reg
reg export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ShadowProtectSvc\Parameters\do c:\SPDestinations.reg

After you migrate:

First, reactivate ShadowProtect using your license key. Next, before taking a new backup, copy the C:\SP*.reg files to the VM, and then in windows explorer double click the .reg files to import them into the registry. Then reboot so that the new registry entries will take effect after the ShadowProtect service starts again.
