Abstract

A system and method for automating the migration of configuration settings and data from computer systems running the Linux operating system to computer systems running the Windows operating system. The invention utilizes data from one or more sources to create the configuration of the target system, and translates between settings related to the Linux systems and Windows systems involved. As a result, it simplifies the otherwise complex and time-consuming task of migrating from one server to another, specifically when migrating between two operating systems that provide similar functionality but are configured in distinctly different ways.

Claims

1. A method for automatically migrating from a Linux server to a Windows target server, comprising:

automatically extracting Linux configuration information pertaining to Linux services hosted by a Linux server;

automatically generating Windows configuration information for a Windows target server to support Windows services that are analogous to the Linux services hosted by the Linux server; and

automatically installing appropriate Windows components and configuration files on the Windows target server to perform the analogous Linux services in view of the Windows configuration information that is generated,

wherein the automatic migration includes automatically migrating OpenLDAP (Lightweight Directory Access Protocol) configuration information on the Linux server to corresponding Windows Active Directory information on the Windows target server.

2. The method of claim 1, wherein the analogous services include file share services, the method further comprising:

extracting Linux file share information from Linux file share configuration information stored on the Linux server;

translating the Linux file share configuration information into corresponding Windows registry entries; and

storing the Windows registry entries on the Windows target server.

3. The method of claim 1, further comprising:

automatically migrating data files stored on the Linux server to the Windows target server.

4. The method of claim 3, further comprising:

generating a backup of the data files that are migrated.

5. The method of claim 3, wherein migrating the data files comprises:

copying the data files from the Linux server to the Windows target server; and

deleting the data files on the Linux server.

6. The method of claim 5, further comprising:

scanning the data files for viruses; and

not copying a data file to the Windows target server if the data file is detected to have a virus.

7. The method of claim 1, further comprising:

determining a network name for the Linux server; and

renaming the Windows target server with the network name of the Linux server.

9. The method of claim 1, wherein migrating the OpenLDAP information comprises:

extracting OpenLDAP information from an OpenLDAP database hosted by the Linux server; and

replicating the OpenLDAP information in a Windows Active Directory repository hosted by the Windows target server.

10. The method of claim 1, further comprising:

enabling a user to selectively undo all or a portion of a migration process.

11. The method of claim 1, further comprising:

searching a network to identify Linux and potential Windows target servers connected to the network; and

enabling a user to select a Linux server comprising a migration source and a Windows target server comprising a migration target, wherein configuration information is migrated from the migration source to the migration target.

12. The method of claim 1, further comprising:

storing the Windows configuration information in a repository; and

retrieving the Windows configuration information from the repository; and

installing appropriate Windows components and configuration files on multiple Windows target servers to perform the analogous Windows services in view of the Windows configuration information that is retrieved.

13. The method of claim 1, wherein installation of the appropriate Windows components and configuration files on the Windows target server includes automatically installing a Windows operating system on the Windows target server.

14. The method of claim 1, wherein the Windows target server comprises a Windows server running an instance of the Windows operating system prior to initiation of the migration process.

8. (canceled)

15. A machine-readable medium to provide instructions, which if executed perform operations to facilitate migration from a Linux server to a Windows server, the operations including:

extracting Linux configuration information pertaining to Linux services hosted by a Linux server;

migrating OpenLDAP (Lightweight Directory Access Protocol) configuration information on the Linux server to corresponding Windows Active Directory information on the Windows target server;

generating Windows configuration information for a target server to support Windows services analogous to the Linux services hosted by the Linux server, the Windows configuration information including Windows registry entries; and

installing, in view of the Windows configuration information that is generated, the Windows registry entries and appropriate Windows components on the target server to enable the target server to perform the Windows services that are analogous to the Linux services.

16. The machine-readable medium of claim 15, wherein the instructions are embodied as a carrier-wave file.

17. The machine-readable medium of claim 15, wherein the Windows services that are analogous to the Linux services include file share services, and execution of the instructions performs further operations including:

extracting Linux file share information from Linux file share configuration information stored on the Linux server;

translating the Linux file share configuration information into corresponding Windows registry entries; and

storing the Windows registry entries on the target server.
