This is a pseudo-followup from my previous NetWare migration post. For customers looking to migrate from GroupWise to Exchange server (or, in the interest of equal-time, to another mail system
) have more resources at hand than they probably thought. Many times I speak with customers who are not sure of what kind of support Microsoft provides and what resources are available to assist with their migration and coexistence strategies.
I’m amazed at the number of people who don’t know that we include a very good set of tools “in the box” with Exchange Server. In Exchange Server 2000 and Exchange Server 2003, there is something called the “Exchange Connector for GroupWise”. This handy little piece of software allows a customer to maintain synchronization between the GroupWise Address Book and Active Directory. This allows users in one system to see users in another system as if they were all using the same mail system. In addition, the connector will route mail from one system to another – including tasks and calendar items. Even free/busy information is replicated across this connector allowing a user in one system to query the calendar of a user in the other system and find an appropriate meeting time. And when you’re ready to migrate users from GroupWise to Exchange, you can use the built-in migration utility to do just that! An incredibly oversimplified view of the process looks a little like this:
- Install/Configure destination Exchange environment.
- Install/Configure Exchange Connector for GroupWise.
- Make sure that directory synchronization, mail flow and free/busy information is correctly going both ways over the connector.
- Migrate users from GroupWise to Exchange either one at a time or in groups. During the migration process, users in one system should still be able to get mail to/from users in the other system seamlessly.
- When the migration is complete, the GroupWise system and the Connector components can be removed.
You can find all sorts of migration and inter-operability resources for Exchange and GroupWise at http://www.microsoft.com/technet/prodtechnol/exchange/2003/library/interopmig.mspx.
So, once customers find this out they’re very optimistic
until I tell them the “gotchas”. For one, we only “officially” support GroupWise 5.5 and earlier with the tool. This is an unfortunate oversight on the product group’s part (in my humble opinion!) and is due to be rectified very soon from what I hear. The tool will still work with GroupWise 6.X installations in most instances based on my experience – except that HTML-based mail doesn’t always get converted properly by the connector. The “in the box” tools also won’t do things like migrate personal address books or GroupWise Archives. It’s the 80% rule, folks. Build into the product what 80% of the world needs and count on a strong ecosystem of partners to come up with the other 20%.
That’s just what two companies, Wingra Technologies and CompuSven specialize in doing. Both have migration software that bridges the gap between what’s in the box and what more sophisticated customers need. Both also, according to their website, support newer versions of GroupWise. They provide nice features like address book and archive conversion as well as better reporting and scheduling capabilities for administrators during the migration process. If what’s “in the box” doesn’t do it for you, you should check these additional resources out.
