Migrating Novell GroupWise to Linux

  1. 1. Migrating Novell ® GroupWise to Linux ® Robin Redgrave Tim Heywood Collaboration Technical Specialist CTO, NDS8 rredgrave@novell.com tim.heywood@nds8.co.uk
  2. 2. Agenda • Preparing to migrate • Manual Migration vs. Wizard Migration • Domain Migration • Post Office Migration • What’s going on behind the scenes • Troubleshooting • Question and Answer 2 © Novell, Inc. All rights reserved.
  3. 3. Planning the Migration • Health Check first • Contents check on all post Offices – Resolve all problems and errors 3 © Novell, Inc. All rights reserved.
  4. 4. Planning the Migration • Planning – Is hardware being replaced? – New hosts virtualised? 4 © Novell, Inc. All rights reserved.
  5. 5. Special Considerations • Case sensitivity – On Linux, Novell GroupWise , will expect all lowercase ® ® filenames • Management – You need to decide how to access your GW domain > ConsoleOne on the Linux server ® > ConsoleOne on Windows workstation 5 © Novell, Inc. All rights reserved.
  6. 6. The Migration
  7. 7. Manual Migration vs. Wizard • Manual Migration is “easy” - if you understand Linux • Wizard is more “hidden” – More things to “go wrong” – Much easier if you aren't that comfortable with Linux 7 © Novell, Inc. All rights reserved.
  8. 8. Manual Migration • Install the Agents on the Linux Server • Copy Novell GroupWise data to Linux Server ® ® • Configure the Agents • Load the Agents Sounds simple huh? 8 © Novell, Inc. All rights reserved.
  9. 9. Wizard Migration • Run the Wizard Sounds even more simple 9 © Novell, Inc. All rights reserved.
  10. 10. Manual Migration vs. Wizard • If it's that simple why don't we just use the wizard? – Path... – There is no control over the destination – Log File locations – Clustering 10 © Novell, Inc. All rights reserved.
  11. 11. Manual Migration
  12. 12. Prerequisites • A Linux Server • NCPFS on Linux Server * – This allows you to mount a drive to a NetWare Server ® • SMBFS on Linux Server * (usually there by default) – This allows you to mount a drive to a Windows Server • Adequate Disk Space for Migration • Novell GroupWise Linux software ® ® • ConsoleOne and snapins on Linux server ® * Depending on what you are migrating from 12 © Novell, Inc. All rights reserved.
  13. 13. Which File System • Recommended Choices – NSS – EXT3 – Reiser – EXT3 with H-Tree? > Currently avoid – XFS > Currently avoid 13 © Novell, Inc. All rights reserved.
  14. 14. Which Linux? • Open Enterprise Server – Manageability > Integrated with Novell eDirectory ® ™ > Novell client / NCP access to all file systems ™ > Linux User Management > Novell Remote Manager – Novell Cluster Services ™ • SUSE Linux Enterprise Server ® – One free server license with Novell GroupWise purchase* ® * - “Or as many as your Novell GroupWise system Requires” 14 © Novell, Inc. All rights reserved.
  15. 15. Data Preparation Belt, Braces and Binder Twine! Run a change case utility to make all files lower case before you start http://www.febooti.com/ 15 © Novell, Inc. All rights reserved.
  16. 16. Server Configuration • Install SUSE Linux Enterprise Server and ® partition disk – Partitioning scheme > boot – ext3 – 5GB+ > swap 2GB > /var – 10 GB > /srv GroupWise data partition ® » dbcopy, 3 times post office size » tsafsgw, 2 times post office size > /srv/backup or /srv/restore partition is an option – Logical vs. primary > Only four primary partition permitted (primary or extended) » Multiple extended partitions? » LVM or EVMS? 16 © Novell, Inc. All rights reserved.
  17. 17. Accessing File Systems • Use NCP to access domains on NetWare servers or ® OES2 Linux servers • Use SMB/CIFS to access domains on SUSE Linux ® Enterprise Server or Windows servers • Using NFS will result in File Lock (820E) errors – (or is that OK?) 17 © Novell, Inc. All rights reserved.
  18. 18. Moving Your Post Office • Phase One – Install agent software on your Linux server for all objects you plan to migrate > Agents > GWIA > WebAccess Agent > WebAccess Application – Make sure ngwguard.db is lower case before running – Mount a drive to your NetWare server ® > ncpmount -S server -A 123.123.123.123 -U userid -P password /mnt/netware/server • NCPFS is slow 18 © Novell, Inc. All rights reserved.
  19. 19. Moving Your Post Office • Use DBCopy – Run dbcopy to make first pass copy of the post office > dbcopy –p –m –f –k <source> <destination> > –p Post Office Migration > –m This is a migration – storelowercase and case conversion > -f First pass of a migration > -k do not calculate database sizes etc. – The first pass copy can be run days prior to the final copy, or immediately preceding 19 © Novell, Inc. All rights reserved.
  20. 20. Configuring Post Office • Configuring Agent – Creates POA startup file – Configures gwha.conf • Start POA on Linux server for testing – /opt/novell/groupwise/agents/bin/gwpoa @startup.poa –show • Watch via the “-show” window • Connect to test – specify the IP address • Shut down this POA 20 © Novell, Inc. All rights reserved.
  21. 21. Post Office Migration – Phase Two • Stop the source Post Office Agent • Edit Post Office configuration – Post Office UNC path (do this first) – POA IP address – POA Platform – Ports (if needed) – Log file path – SSL cert/key file paths – Remote Library Storage area path – LDAP server Trusted Root certificate for LDAP authentication 21 © Novell, Inc. All rights reserved.
  22. 22. Post Office Configuration– Phase Two • Rebuild the PO – Rebuild to c:temp – Rename the old wphost.db – Copy the new wphost.db 22 © Novell, Inc. All rights reserved.
  23. 23. Migrating Post Office – Phase Two • Use DBCopy – Run dbcopy to make the second pass copy of the post office > dbcopy –p –m –s –k <source> <destination> > –p Post Office Migration > –m This is a migration – storelowercase and case conversion > –s Second pass of a migration > –k Still do not calculate database sizes etc. • DO NOT USE –l or -o switches! 23 © Novell, Inc. All rights reserved.
  24. 24. Remote Library Storage Area • May need to manually copy remote library storage area to Linux server • Modify storage path in ConsoleOne ® • Do this before starting the POA 24 © Novell, Inc. All rights reserved.
  25. 25. Post Office Migration • Start the POA on the Linux server, verify that you can log in and send mail in and out of the GWIA – and to another post office on another server 25 © Novell, Inc. All rights reserved.
  26. 26. Migrating Domains and Gateways
  27. 27. Domain Migration • Gateways – Kill or Keep? – If you have other Gateways running GWIA etc > Kill – Cleaner in the new environment – No other Gateways > Kill – Create temporary gateways – If you really insist – yes it will work YMMV 27 © Novell, Inc. All rights reserved.
  28. 28. Domain Migration • The Domain does not require a two step migration process, because it is typically a “fast” process – Clean out queues from “old” and invalid information – Clean out “problem” and “log” directories – Stop the GWIA – Stop the GWINTER – Stop any other gateways – Delete the Gateways (save the gwac.db first) – Stop the MTA 28 © Novell, Inc. All rights reserved.
  29. 29. Migrating the Domain • Mount your source server • Run dbcopy –d –m <source> <destination> –d domain copy –m migration 29 © Novell, Inc. All rights reserved.
  30. 30. Domain Migration • In ConsoleOne , change the IP ® addresses and paths for all migrated objects (including gateways) • Verify the link configuration for the migrated domain 30 © Novell, Inc. All rights reserved.
  31. 31. Domain Migration • Edit domain configuration – Domain UNC path – MTA IP address – MTA Platform – Ports (if needed) – Log file path – Message log path (if enabled) – SSL cert/key file paths – Run the Agent Configuration module from the Linux Install application 31 © Novell, Inc. All rights reserved.
  32. 32. If you MUST migrate Gateways
  33. 33. Gateways – GWIA • Edit GWIA settings in ConsoleOne ® – Change Platform to Linux – Modify NetWork Address settings > Bind Exclusively to TCP/IP Address » Allows coexistence with Postfix (Watch out for SLES10 SP3) – Modify /dhome path (if not in current gwia.cfg) – Modify Log path – Modify SSL path > May need to create new certificates for new server • Change MX record to point to new DNS name • Run the GWIA configuration module in the Linux installation program 33 © Novell, Inc. All rights reserved.
  34. 34. Gateways – WebAccess • If running remote, edit starup file to point to new UNC for the new domain location • Configure the WebAccess Agent with the Installation software • Install and Configure WebAccess application on Linux Server – If application is on another server, copy commgr.cfg to application directory to use new agent IP address 34 © Novell, Inc. All rights reserved.
  35. 35. Domain Migration Start the MTA Start the Internet Agent Start the WebAccess Agent 35 © Novell, Inc. All rights reserved.
