Abstract

Claims (50)

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

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

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

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

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

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

extracting Windows® file share information from Windows® registry entries stored on the Windows® server;

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

storing the Linux® file share configuration information in a Linux® file share configuration file on the Linux® target server.

3. The method of claim 1 , further comprising:

automatically migrating data files stored on the Windows® server to the Linux® target server in a manner that preserves security information for the migrated data files.

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 Windows® server to the Linux® target server; and

deleting the data files on the Windows® server.

6. The method of claim 5 , further comprising:

scanning the data files for viruses; and

not copying a data file to the Linux® 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 Windows® server; and

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

8. The method of claim 1 , wherein migrating the Windows® Active Directory information comprises:

extracting Windows® Active Directory information from an Active Directory database;

replicating the Windows® Active Directory information in an OpenLDAP (Open Lightweight Directory Access Protocol) repository hosted by the Linux® target server.

9. The method of claim 1 , further comprising:

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

10. The method of claim 1 , further comprising:

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

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

11. The method of claim 1 , further comprising:

storing the Linux® configuration information in a repository; and

retrieving the Linux® configuration information from the repository; and

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

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

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

14. A tangible computer readable storage medium having stored thereon a set of instructions, when executed by a computer, cause said computer to perform operations to facilitate migration from a Windows® server to a Linux® server, the operations including:

extracting Windows® configuration information pertaining to Windows® services hosted by a Windows® server;

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

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

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

15. The tangible computer readable storage medium of claim 14 ,

wherein

the Linux® services that are analogous to the Windows® services include file share services, and execution of the instructions performs further operations including:

extracting Windows® file share information from Windows®

registry entries stored on the Windows® server;

translating the Windows® registry entries to corresponding

Linux® file share configuration information; and

storing the Linux® file share configuration information in a

Linux® file share configuration file on the target server.
