I work for a company that handles the email accounts for their clients. We were migrating from one email service provider to another and had to transfer all of their mailboxes. 24 mailboxes. The smallest one had 22 GB of mail in it. The largest had over 90 GB.
Client: We need this mail migrated as quickly as possible.
Me: Okay, I’m working on the migration now. Transferring the mail between the two services is going to take a considerable amount of time.
Client: Define considerable? Like… 30 minutes?
Me: Um… no. There’s over a terabyte of mail that needs to be moved. Even if we sustain a gigabyte of transfer a minute, it would still not be done in less than 20 hours.
Client: 20 hours? Unacceptable. I need you to find a way to have it done in the next hour.
