Benefit from the hard-won experience gained by Novell Consulting in dozens of Novell Open Enterprise Server 2 upgrades. In this session, we will discuss the methodologies successfully used with both large and small customers. We'll also discuss prerequisites, environmental preparation, migration strategies and post-migration cleanup. Handouts containing a pre-migration discovery survey and a migration checklist will be provided.

  • 1. Upgrading from NetWare to Novell ® ® Open Enterprise Server on Linux: The Novell Consulting Way Ryan Kensrud Michael Saunders Senior Technical Specialist Senior Technical Specialist rkensrud@novell.com msaunders@novell.com
  • 2. What Is the Novell Consulting Way? ® • Develop a methodology to migrate your NetWare environment ® – Not just servers, but services and in which order • Develop a repeatable process for your servers • Lab test the process until success is assured – Lab must mirror production as close as possible – Use images of production servers in lab (Xen, Portlock, VMware, etc.) – Isolate lab from production network physically and logically • Develop user communication and change control • Develop back-out procedures that return NetWare to production if required 2 © Novell, Inc. All rights reserved.
  • 3. Why Migrate from NetWare to ® Novell Open Enterprise Server 2? ® • Support for NetWare is going away – Novell support® > 3/7/2010 - End of standard support > 3/7/2012 - End of extended support > 3/7/2015 - End of self support > All current and future development is for Linux > We will not leave migrating customers hanging – Hardware support > Server vendors are no longer certifying NetWare for new hardware > LAN / HBA vendors are no longer writing drivers 3 © Novell, Inc. All rights reserved.
  • 4. Why Migrate from NetWare to ® Novell Open Enterprise Server 2? ® • Support for NetWare is going away (continued) – Utility software support > Anti-Virus vendors will shortly stop providing DAT file updates > Tape-backup vendors will shortly stop certifying solutions for new tape hardware • Other reasons – Qualified staff > Education and training for Linux is easier to find than for NetWare > Entry level IT professionals are more likely to know Linux than NetWare 4 © Novell, Inc. All rights reserved.
  • 5. Why Migrate from NetWare to ® Novell Open Enterprise Server 2? ® • Other reasons (continued) – Innovation has been on the Linux platform > Dynamic storage technology > Novell iFolder 3.x > Domain services for windows > Xen services – Take advantage of modern hardware > OES2 is a 64 bit OS > Able to use more CPU cores > Able to use virtualization features of CPU 5 © Novell, Inc. All rights reserved.
  • 6. Tenets of a Migration • Source environment must be clean, ready, and stable • Novell Open Enterprise Server 2 configuration must ® be complete and accurate – OES2 is less tolerant of misconfiguration than NetWare was ® • Most migration operations run directly on the target server as a “pull” operation • Most migration operations are a non-destructive copy • Use DNS for everything • Use a checklist during migrations • Bulk load most of the effort before the migration • Keep the outage window as short as possible (<1 hour) 6 © Novell, Inc. All rights reserved.
  • 7. Overview of Migration Steps
  • 8. Step 1: Prepare Your Environment • All servers should be running a supported OS – NetWare 5.1 sp8, or NetWare 6.5 sp7/8 ® – Novell Open Enterprise Server 1 sp1 ® • Novell eDirectory should be 8.7.3.9+ or 8.8+ ™ on ALL servers – 8.6 seems to work but it is unsupported • Verify all software in use is compatible with eDirectory 8.8 – Novell ZENworks 2.x, Identity Manager 3.x, no IPX, etc. • Perform a complete eDirectory health check • Clean up stale login scripts • Delete stale data 8 © Novell, Inc. All rights reserved.
  • 9. Step 2: Plan Your Migrations • Map out a server consolidation plan – 1:1 at small sites unless WAN will carry consolidation – 4:1 average at data centers – Consolidate SLP, LDAP, and replica servers • Map out a sequence for servers and services – Certificate authority and LDAP should be first to move – SLP DA services should be last to move – Start with utility servers that have redundancy (replica, ldap, etc.) – Move smaller work group server next as a pilot – Finish with critical file and print servers 9 © Novell, Inc. All rights reserved.
  • 10. Step 2: Plan Your Migrations (continued) • Plan user facing changes – How to deal with login scripts > Server names likely changed if consolidating > Volume names and paths likely changed if consolidating > Copy and paste in text files. Easy to back-out changes > Consider using Directory Map Objects (DMO) instead of UNC – Client 32 upgrades and changes > Should be at least version 4.91 sp4 > Now is the time for the scripted install with auto-update for future > Is login server still correct or required? (requires NCP name, not DNS) > Change SLP and LDAP to DNS entries pointing to existing servers – iPrint agent and printer deployments if necessary (using DNS) 10 © Novell, Inc. All rights reserved.
  • 11. Step 3: Create a Server Build Process • Recommend using a network source for files – It's faster than DVD and will ensure all servers are the same – Build an SMT patch source to cache updates locally • Create a proxy user account for server builds – Password never expires, account never gets deleted • Use a build process document or scripted install • Prepare a Linux User Management (LUM) design • Pre-populate DNS with entries for servers and services – iPrint managers, LDAP servers, SLP DA, time source, etc. 11 © Novell, Inc. All rights reserved.
  • 12. Step 4: Build Your First Server • Configure Linux User Management (LUM) • Patch the server via online updates or internal SMT • Use it for your LDAP server during subsequent server installs (using DNS for LDAP service) • Move your Certificate Authority to this server – Follow TID 3618399 – Be aware of the following links if you loose your CA > http://www.novell.com/coolsolutions/appnote/18424.html > http://www.novell.com/communities/node/5704/certificate-recreation-script-oes1-and-oes2 12 © Novell, Inc. All rights reserved.
  • 13. Step 5: Build Subsequent Servers • Follow the build documentation • Use Pre-migration option if doing Transfer-ID method • Cluster the servers if able • Configure Linux User Management (LUM) • Patch the server via online updates or internal SMT – Especially migration tools • Install all desired services including tape backup, anti-virus, monitoring, etc • Test all services before users are moved and affected 13 © Novell, Inc. All rights reserved.
  • 14. Step 6: Execute Migrations • Use your checklist for every action • Be familiar with your back-out plan and prepared to execute it each time – You did perform a backup right? • Have a subset of users from the business available post migration to test and sign-off • Have a plan to retire old server (don't allow changes to migrated data) 14 © Novell, Inc. All rights reserved.
