So when C2C published a white paper on using an e-mail archiving system to help with an Exchange server migration, I was interested.If you are still using Microsoft's Exchange 5.5 servers and looking to update or migrate to something else before Microsoft stops supporting the product on December 31, C2C has some helpful advice.
Any migration project requires careful planning and preparation, but your e-mail archiving system can help reduce the headaches. If you are using C2C's or any e-mail archiving product, for that matter, those products usually impose housekeeping rules that can smooth the migration process. Not to mention the fact that policy- and capacity-based archiving can drastically reduce those oversized mailboxes and lessen the load of messages and folders that need to be migrated.
And come to think of it, what better time to implement an e-mail archiving system if you haven't already. If you have to perform a migration, why bring all the errors and compliance risks forward onto the new server?
For instance, migrations are notorious for highlighting all your "zombie accounts" of users that should no longer be in the system, and users with outdated permissions profiles. Cleaning those up ahead of time makes the migration easier.
An archiving system can also compress attachments, which can reduce your migration time and improve the performance of the messaging system.
