  • 4. Before Starting the Migration
  • 5. Reasons for Migrating End of NetWare General Support ® 3rd party support has waned March 7, 2010 – Start extended support New Features Dynamic storage technology, Domain Services for Windows Virtualization Enhanced scalability – 64-bit support Linux and Open Source New possibilities Linux certifications 5 © Novell, Inc.

  • 11. Novell Open Enterprise Server ® Things to Think About
  • 12. Novell Open Enterprise Server ® Things to Think About Standards • Define and Follow your “new” standards • Linux is case sensitive (User, Groups and other objects) Naming • Uniqueness • Local EXT3 and LVM File System Layout • /boot / (root) /tmp /var /home Packet / Pattern • Install only what is really required and used Detection • 1. Install, 2. Patch, 3. Configure LAN Connectivity • Use Bonding for fault tolerance (active-backup) SAN and Storage • Use DM-MPIO if possible,know if it is cluster or stand- alone Connectivity • Verify certification of storage infrastructure for SLES 12 © Novell, Inc. All rights reserved.
  • 13. Novell Open Enterprise Server ® Things to Think About Name •DNS (same as on NetWare) •Changes in SLP (move to OpenSLP) Resolution •HOSTS Timesync •Move from Timesync to NTPD eDirectory ™ •NMAS + Universal Password + Password Policies •Implement Universal Password for AFP and CIFS? Linux User •For what do we need LUM? •Convert lower, persistent search, cache only, alternate Mgmt servers LDAP Proxy •Where to put them in eDirectory? •Install user vs. LDAP proxy users •One proxy user per service per location / server Users •Security DHCP •LDAP integrated “Linux” DHCP 13 © Novell, Inc. All rights reserved.
  • 14. Novell Open Enterprise Server ® Things to Think About DNS •Same as on NetWare ® •Novell Storage Services File Services ™ •Distributed File System •Dynamic Storage Technology File Access •NCP / CIFS / AFP / NFS / NetStorage ™ •CPFL & DFS / DST Support Protocols •Pure-FTP + Gateway •One driver store only iPrint •Use DNS for Print Manager name resolution •Use DSServer2/DSServer3 for LDAP fault tolerance iManager •Install only where required •Keep plugins current Cluster Services •See Novell Cluster Services Session ® 14 © Novell, Inc.

  • 15. Migration Processes: Step-by-Step
  • 16. Migration Step-by-Step eDirectory Server ™ Install New Server Uninstall Add Replicas Old Server Verify and Change Monitor Replica Type Change Login Move CA and Process Verify SDI Move IDM Driversets To Rollback – just reverse the process 16 © Novell, Inc. All rights reserved.
  • 17. Migration Step-by-Step Cluster (Rolling Upgrade) Remove Advantages NetWare Node •No new hardware •Less effort Do Final Conversion after Re-add Server all nodes as a Linux Node are Linux Disadvantage •High risk Migrate Repeat steps 1-3 Resources to for all Nodes Linux Node 17 © Novell, Inc. All rights reserved.
  • 18. Migration Step-by-Step Cluster (Build a New Cluster) Advantages Build New Linux Cluster •Lowest Risk •Chance for re- design, consolidation & Test Congratulate yourself on Move Data using Migration a successful Migration! Toolkit or SAN Replication Disadvantage •More Effort Remove old Servers Change Login Script/ from the tree and clean DNS Entries, UNC paths up eDirectory ™ 18 © Novell, Inc. All rights reserved.
  • 19. Migration Step-by-Step Remote Server / Special Purpose •Assign the zones to the new DNS server DNS Migration •Reconfigure clients & servers DHCP •Use Migration Toolkit Install New Server •Clean up before migrating Migration •Use Migration Toolkit •Disable Login & Clear connections for final delta- File Migration sync •Modify Login Scripts Uninstall Move / Migrate iPrint •Use Migration Toolkit Old Server each Service •Copy/Consolidate and change DNS Migration •Remove old queues and gateways User Migration •Move User per user /department based •Find and Remove existing dependencies Dependency •use DNS (CNAME) where possible Cleanup •use loginscript 19 © Novell, Inc.

  • 20. Migration Processes: Transfer-ID
  • 21. Migration “Transfer-ID” eDirectory Server ™ Install New Server Install into the same context as Install Pre-Migration Pattern the Source Use Migration Tools Transfer eDirectory and Identity Verify Log Files Post-Migration and Cleanup Clean Up eDirectory Check eDirectory 21 © Novell, Inc. All rights reserved.
  • 22. Migration “Transfer-ID” Cluster Node Not needed! 22 © Novell, Inc. All rights reserved.
  • 23. Migration “Transfer-ID” Remote Server / Special Purpose Install New Server Install Services that will Install Pre-Migration Install into same context Migrate (NSS, iPrint) Pattern as Source Use Migration Tools Transfer eDirectory ™ Transfer Services - File, Verify Log Files and Identitity Print, iFolder, DHCP Post-Migration & Cleanup Clean Up eDirectory Configure and Check Services 23 © Novell, Inc. All rights reserved.
  • 24. Transfer-ID vs. Step-by-Step Transfer-ID Comparison Advantages Disadvantages • No new name or IP • High Risk Address required • No easy rollback • No change in login scripts • No chance to test required • No chance to increase the • No change in eDirectory ™ load attributes required • No chance to re-design • Fast 24 © Novell, Inc. All rights reserved.
  • 25. Transfer-ID vs. Step-by-Step Recommendation and Best Practice • Start with Step-by-Step and use Transfer-ID later • Find and remove your dependencies • Remove forgotten “old, inherited stuff” • Split services logical from server names • Review your design and re-design • Use DNS Name resolution where possible • Use secondary IP-addresses • Note: Transfer-ID only migrates some applications 25 © Novell, Inc.

  • 29. Migration Tools Features Migrates Service Migrations Several OES File System Services iPrint CLI Tools Transfer-ID Migration CIFS AFP Migration DHCP Tools FTP Non- iFolder destructive migration and consolidation Scheduling NTP Archive & Versioning E-mail Notification 29 © Novell, Inc. All rights reserved.
  • 30. File System: Migration Procedure •Many Command Line parameters (see migfiles) •The GUI uses a SCMT like approach –Drag/drop directories or volumes to the target –Select date/time or pattern based filters •Uses SMS and nbackup to move data –System meta data preservation = SMS Backup 30 © Novell, Inc. All rights reserved.
  • 31. File System: Tips and Tricks Load TSAFS with /cluster and /showclustervolumesonnode on the source server Use NSS /NOQUOTACHECKING on the target server 31 © Novell, Inc. All rights reserved.
  • 32. iPrint: Migration Procedure iPrint data migrated • Printer objects, printer drivers, driver profiles, print managers, ACL's, banners and printer pools Using the GUI • Select the active print managers on both the source and the target • Select all or required printers to migrate Printer Migration Naming • Printers can keep the same name and context in eDirectory . The original eDirectory print objects are ™ renamed 32 © Novell, Inc. All rights reserved.
  • 33. iPrint: Migration Key Points • TID 7004455 is the official iPrint migration best practices guide • The Migration tool for iPrint – Requires successful iprntman authentication – Creates duplicate printer objects (NetWare to Linux) ® – Option to “migrate” objects to same container (rename _NW) – Is a non-risk procedure if choosing 'Consolidate' – Creates /opt/novell/iprint/bin/psmimport.xml – Does not configure workstations to point new print manager 33 © Novell, Inc. All rights reserved.
  • 34. iPrint: Workstation Migration iPrint printers installed to workstation consist of the following: • Printer agent name (without eDirectory™ context) • Address to which Print Manager is bound Two strategies to point installed printers to a new server: ● Address binding (TID 7005255) – PSMHostAddress value within etc/opt/novell/iprint/conf/ipsmd.conf ●iPrint printer agent redirection (TID 3006726) 34 © Novell, Inc. All rights reserved.
  • 35. DHCP: Migration Procedure • NetWare DHCP configuration is mapped to ® Linux DHCP – The NetWare schema and Linux schema in eDirectory are ™ different – All the subnets get migrated inside a single DHCP service (dhcpService object) including leases • The GUI and the CLI support three levels of migration – Server Level: Migrates NetWare server with all the associated subnets – Subnet Level: Migrates the selected NetWare subnets only – Tree Level: Migrates all the servers in the tree with the associated data 35 © Novell, Inc. All rights reserved.
  • 36. After the Migration to Novell Open Enterprise Server ®
  • 37. Activation / Implementation of NEW Features Wait some time before new features are activated Implement any Make sure the additional features migration was (DST, DFS, DsfW, successful ifolder) Fix any problems Monitor the system 37 © Novell, Inc. All rights reserved.
