We use Migrationwiz.com almost exclusively for on-boarding (and when the need arises off-boarding) mailboxes to the Cobweb Hosted Exchange service. I have previously blogged about this, but it makes everything a lot simpler and overcomes a number of hurdles traditional on premise or PST migrations will encounter. Our customers have noticed and often comment on how smooth the whole process is.
A sticking point has been migrating from non-Exchange servers such as Google Apps where user credentials must be supplied for each mailbox. They have a fantastic password gathering service, which although secure has raised questions about sending users to a “new” web site requesting passwords. Well, this is no more thanks to a new addition on Migrationwiz.com enabling use of the Google Apps OAUTH domain key and secret to access mailbox data.
For more information on visit the Migrationwiz.com wiki, How do I migrate from Google using administrative credentials?
If you want someone to manage the migration for you and are looking for a Hosted Exchange provider head over to http://www.cobweb.com. If you fancy migrating yourself we all Cobweb Hosted Exchange settings are already loaded in to provider list on Migrationwiz.com.
