Does anyone have any time refrences on how long it takes to convert a Notes mailbox to an Exchange mailbox. For example, if I have a 100MB Lotus Notes mailbox, about how long will it take to migrate it to Exchange?

Depends on several items:
1. Speed of Exchange Server
2. Speed of Domino Server
3. Network speed between the two systems.
4. How complex the messages are. The migration wizard moves a message at a time.
5. The migration approach taken.

Bestsolution to perform a 2 phase migration using the Exchange Migration Wizard for both phases.

1. Migrate the mail account NSfs over to respective PST files.
2. Import the PST files into Exchange.

Why use a 2 phase approach, if a problem with the migration occurs you can always delete the accounts and start again from the PST. Also its quicker.

On fairly moderate speed systems (550mhz-750mhz) I've migrated over approx 5gb (approx 50 mailboxes) of data in about 4 hours of time using the2 phase approach.

Good luck
