2. March 6, 2006 Part 3 – Server Migration Description of migration process Migrating Users & Groups Migrating File Shares Migrating Printers Demos

3. March 6, 2006 Migration Overview Migrate a Windows server to Samba Can migrate several types of service −Domain controller (i.e. logons) −File server −Print server Separate tools for migrating each type of service

4. March 6, 2006 Migration Steps 1.Prepare target Samba server 2.Clean up source Windows server 3.Perform migration 4.Cleanup and testing 5.Swap over service

5. March 6, 2006 Migrating Users & Groups Migration of domain logons Use net rpc vampire tool NT4 and Windows 2000 mixed mode domains only! Samba 4 to support vampire of AD domains

6. March 6, 2006 Prepare Samba Server Start with empty Samba configuration Configure add user/group scripts in smb.conf −add user script −add group script −add user to group script Join to domain as BDC Copy domain SID from domain controller −net rpc getsid -S SERVER

7. March 6, 2006 Clean up Windows Server Remove unused users and groups May need to modify user and group names if migrating to strict POSIX Samba server

8. March 6, 2006 Perform Migration net rpc vampire -S SERVER Muchos output created Probably many error messages Not the most friendly user interface Migrates −Users and groups −Group membership −Passwords −Account status −Password history

9. March 6, 2006 Demo

10. March 6, 2006 Migrating File Shares Replicating a file share −And the share ACL Replicating file and directory structure of a share −And the file and directory ACLs

11. March 6, 2006 File Copying Utilities Windows utilities −robocopy.exe −scopy.exe −Windows Explorer! Linux utilities −smbclient −net share migrate Microsoft File Server Migration Toolkit −Untested, may not work

12. March 6, 2006 Perform Migration Clean up unused or unwanted files first net share migrate This tool can migrate: −shares −share security −files and directories −file security

13. March 6, 2006 Demo

14. March 6, 2006 Migrating Printers Use Microsoft's Printer Migrator v3.1 Supported in Samba 3.0.20 and up printmig.exe Backs up and restores −printers −queues −permissions −drivers Very hard to get working

15. March 6, 2006 MS Print Migrator Tips User performing the migration must have admin access to the printer −Grant them the SePrintOperatorPrivilege enable asu support = no Create a share called admin$ −\system32\spool\drivers points at print$ Check that migration user can write to files in the admin$ share Bon chance!

16. March 6, 2006 Migrating Printers Use net rpc printer migrate This tool can migrate −printers −settings −drivers −forms −ACLs

17. March 6, 2006 Migrating Printers (cont) 1.Prepare Samba server 2.Clean up old printers, drivers, etc 3.net rpc printer migrate 4.Profit!

18. March 6, 2006 Demo

19. March 6, 2006 Samba Documentation The Official Samba Howto and Reference Guide Samba by Example Using Samba Manual pages All available online and in print

20. March 6, 2006 Online Resources samba and samba-technical mailing lists #samba and #samba-technical on irc.freenode.net http://wiki.samba.org/ Source code Debug logs

21. March 6, 2006 Summary of Part 3 Can migrate servers by role Migrate users and groups using vampire Migrate files and shares using file copy utilities Migrate printers using net command Still a work in progress
