Thanks, this is helpful stuff. We'll be trying a GW6.5 migration in the next few weeks - about 110 gig of mailboxes and attachments.

Once quick question - when you migrate from GroupWise, you lose the SIS (single instance store) or whatever you want to call it - where an email with large attachments to multiple people includes just 1 copy of the attachment with multiple pointers - so of course on migration your storage requirements increase. Were you able to quantify (for your shop) what percentage jump it was?

thanks,
greg
