why switch
Why Switch?
  • Change in administration and change in expectations…
    • Calendars
    • Mobile device support
  • NetMail futures…
    • Insufficient information / transparency re: Hula to make a business decision.
  • Already contemplating a change to client software for existing solution.
    • Mozilla Suite to Mozilla Thunderbird
why groupwise
Why GroupWise?
  • Relevant experience already on hand…
    • Novell Cluster Services for 3 years
    • GroupWise trial within technology area for 1 year
    • Confidence in our ability to support the solution
  • BlackBerry support recently available.
  • GW 7 client compared favorably with Outlook
  • Cost containment
    • No additional software licensing budget allocated for this project.
    • Administration cost needed to stay at 1 FTE or less
pilot project fall 2005
Pilot project (Fall 2005)
  • Moved all technology staff to GroupWise.
  • President’s Office migrated.
    • Most pressing need was getting the presidential calendar in GW with appropriate proxy access for his staff.
  • BlackBerry Enterprise Server rollout.
    • Technology staff.
    • President.
    • Selected cabinet-level staff.
moving forward formation of a groupwise task force
Moving forward – Formationof a GroupWise task-force.
  • Representatives from all technology areas:
    • Computing and Network Services
      • Systems Administration
      • Enterprise Applications
      • User Support / Helpdesk
    • Instructional Technology Services
      • Training
      • Documentation
    • Administrative Computing
objectives
Objectives
  • Use this as an opportunity to improve email service levels.
    • Implement clustering for fault-tolerance
  • Streamline the migration process
    • Self-service tools.
    • Copious training and support resources
  • Give people a reason to switch
    • Greater enterprise feature set, calendars, mobile devices, etc.
groupwise system design
GroupWise System Design
  • Best practice reference:
    • “Success with Clustering GroupWise 7” - Gregg Hinchman
  • 2 node NetWare 6.5 SP5 cluster built for pilot in Fall 2005
    • Standalone GW system used by University Technology migrated. 1 PO + 1 domain.
    • New primary domain, GWIA, WebAccess, and Employee PO added.
  • 2 nodes and 2 student POs added in March
groupwise system design12
GroupWise System Design
  • Final layout:
    • 4 nodes, 9 cluster resources
      • One primary domain / MTA
      • Two GWIAs / domains
        • Internet mail (SMTP) GWIA
        • GWIA to support IMAP/SMTP clients
      • One WebAccess agent / application / domain
      • GroupWise Messenger
      • Four Post Offices
        • University Technology PO (100 accounts - 50GB)
        • Employee PO (900 accounts, 500 used regularly - 150GB, 1gb mail quotas)
        • 2 Student POs (1,500 accounts each - 150GB each, 200mb mail quotas)
    • GW agents run from clustered volumes and in protected address spaces
groupwise system design13
GroupWise System Design
  • Additional servers and services
    • HP DL360 G3 running Win2K3 for GWGuardian
    • 2 VMWare ESX virtual machines
      • BlackBerry Enterprise Server, GWMonitor service, and IDM Remote Loader for GW
      • SLES 9 Postfix / Mailman server
        • Replacement for NetMail listserv
        • LDAP alias replacement for @alumni.drew.edu forwarding
    • Coming soon / in progress
      • GroupWise Mobile Server
      • GW WebAccess migration to SLES 10
groupwise system design14
GroupWise System Design
  • IDM Integration
    • Where to run the driver?
      • IDM engines running on SLES 9 servers
      • GW driver needs filesystem access to GW domain DB. Remote mount from a linux box is not supported.
      • Solution - Remote Loader service on Windows box, domain DB access over NCP with Client32.
    • Policy decisions
      • Creation - based upon aux class attribute
      • Placement
        • Employee / Technology POs - based on group membership
        • Student POs - Random placement
a phased deployment
A Phased Deployment
  • Phase 1 – Early Adopters
    • March 1, 2006 – May 1, 2006
    • New users were still set up on NetMail by default.
    • Users could “opt-in” through a self-service web site. Faculty/staff only.
    • Migration tools available:
      • Transend Migrator (third-party) for moving IMAP mail and Mozilla address books.
    • University Technology student employees moved to GW for training and support purposes.
a phased deployment16
A Phased Deployment
  • Phase 2 – Full Deployment
    • May 1, 2006 – November 1, 2006
    • New users created on GroupWise.
    • New computers come with GW client preinstalled – all existing images updated.
    • Self-service tools available, GW now available for students. Enhanced migration tools available:
      • Home-grown server-side IMAP copier
      • Home-grown Mozilla address book converter.
a phased deployment17
A Phased Deployment
  • Phase 3 – Compulsory Migration
    • All remaining GW accounts turned on November 1, 2006.
    • Old NetMail system remains available for migration of old email messages only.
    • Users have until March 1, 2007 to retrieve old messages.
  • Phase 4 – NetMail discontinued
    • March 1, 2007 – Old email server decommissioned.
tools to help with the migration
Tools to help with the Migration
  • Self-service account activation
    • Web-based “wizard” points user to docs, client install instructions, etc. and allows for one-click account activation.
    • Sets up forwarding on the old NetMail system.
    • Creates GW account by toggling aux class attribute which triggers IDM driver.
  • Self-service address book converter
    • Converts exported Mozilla address books into a .vcf format which can be imported into GW.
    • Web-based
    • Developed by a student employee in PHP
tools to help with the migration21
Tools to help with the Migration
  • Self-service mail copy utility.
    • Moves users mail from NetMail to GroupWise using IMAP
    • Web-based
      • Users are presented with a list of folders to migrate
      • Actual migration is submitted and performed as a background task.
        • Users don’t need to keep browser open or wait while migration proceeds.
        • Long-running daemon process maintains a pool of IMAP copier worker processes to complete migration jobs.
    • Developed by a student employee in PHP
aftermath
Aftermath…
  • Customers who were asking for the GW featureset have been very pleased with the results
  • Surprised that compulsory migration (Nov. 1st) did not trigger a substantial increase in Helpdesk calls.
  • Some complaints about performance of the Mac client.
  • Unanticipated demand for automatic mail forwarding
  • High GroupWise system reliability.
    • Minor issues with the cluster servers - Java related ABENDs on the WebAccess node.
