Step-by-Step Microsoft CRM 1.2 Migration to CRM 3.0 Part - III
ISSUE# 2
Moving ahead to the next issue you might encounter error: "An error occurred during mapping the computer accounts - the mapping failed" if the “Deployment.xml” file contains mapping of old (in my case it was old CRM server) servers which are not existing in the Active Directory.
<mapping type="computer" role="" dbname="" oldguid="{3fbd6178-2aad-4911-8b46-8f00547de3e0}" newguid="<update manually>" oldname="CN=CRM-OLD-SERVER,CN=Computers,DC=sadad,DC=com" newname="<update manually>" oldsid="S-1-5-21-622582695-539100016-4190993944-1642" newsid="<update manually>" />
To circumvent this problem, you have to delete the above mapping for OLD-SERVERS. Save Deployment.xml and run RedeployWizard.exe successfully.
